Write a program that prompts the user to enter an oligonucleotide sequence, such as TATGAGCCCGTA.

If the user entered a valid oligo sequence consisting only of the characters A, C, G, or T, the program should then display the reverse complement of that sequence, in this case TACGGGCTCATA, along with text indicating that it is the reverse complement .

After displaying the reverse complement, the program should then prompt the user to enter another sequence. The program should continue this pattern of prompting the user for a new oligo sequence and displaying its reverse complement until the user enters a sequence with at least one character that is invalid (i.e. a character other than A, C, G, or T).

Answers

Answer 1

Answer:

Explanation:

The following code is written in Python. It continues looping and asking the user for an oligonucleotide sequence and as long as it is valid it outputs the reverse complement of the sequence. Otherwise it exits the loop

letters = {'A', 'C', 'G', 'T'}

reloop = True

while reloop:

   sequence = input("Enter oligonucleotide sequence: ")

   for x in sequence:

       if x not in letters:

           reloop = False;

           break

   if reloop == False:

       break

   newSequence = ""

   for x in sequence:

       if x == 'A':

           newSequence += 'T'

       elif x == 'T':

           newSequence += 'A'

       elif x == 'C':

           newSequence += 'G'

       elif x == 'G':

           newSequence += 'C'

   print("Reverse Complement: " + newSequence)

Answer: the room had been dark, she had not been able to see him clearly

Explanation:

The word FANCIED means desire or  fancied would mean supposed, believed, or imagined.

The following code segment appears in a class other than Backyard. It is intended to print true if b1 and b2 have the same lengths and widths, and to print false otherwise. Assume that x, y, j, and k are properly declared and initialized variables of type int.

Backyard b1 = new Backyard(x, y);
Backyard b2 = new Backyard(j, k);
System.out.println( /* missing code */ );

Which of the following can be used as a replacement for /* missing code */ so the code segment works as intended?

a. b1 == b2
b. b1.equals(b2)
c. equals(b1, b2)
d. b1.equals(b2.getLength(), b2.getWidth())
e. b1.length == b2.length && b1.width == b2.width

Answers

Answer:

b. b1.equals(b2)

Explanation:

The question has a missing source file (which can be found online).

The function that compares b1 and b2 is:

public boolean equals(Object other) {

if (other == null) {

return false; }

Backyard b = (Backyard) object;

return (length == b.getLength() && width == b.getWidth());

}

Using the function definition, we have:

equals(Object other)

This implies that, the first object will be compared to the second, using the function name.

i,e,

b1.equals(b2)

Hence (b) is correct

In this exercise we have to use the knowledge in computational language in C++ to describe a code that best suits, so we have:

The code can be found in the attached image.

To make it simpler we can write this code as:

public boolean equals(Object other) {

if (other == null) {

return false; }

Backyard b = (Backyard) object;

return (length == b.getLength() && width == b.getWidth());

}

This program will result in the following missing variable:

b1.equals(b2)

Desk checking is a method to check the logic of an algorithm by manually working through it. There are many reasons for Desk Checking that may be omitted or simplified.

What are the reasons for desk checking?

If the current program’s logic is identical, then this step may be omitted; this, however, implies some effort to verify “sameness.” If truly identical, perhaps there is re-usable code, or the code to be developed should become a reusable library routine.

Link testing is the testing of the group of modules in order to ensure that the modules operate correctly in combination. It generally verifies that the function or operation is executed properly. System testing is a type of testing that is used to confirm the actual function of the system in which a work is executed or performed.

Therefore, all of the testing mechanisms are well described above.

Explanation:

Write a Perl program that uses a hash and a large number of operations on the hash. For example, the hash could store people’s names and their ages. A random- number generator could be used to create three- character names and ages, which could be added to the hash. When a duplicate name was generated, it would cause an access to the hash but not add a new element. Rewrite the same program without using hashes. Compare the execution efficiency of the two. Compare the ease of programming and readability of the two.

Answers

Answer:

The Perl code is attached in the attachment. The execution time for using hashes is 0 seconds while that for without hash is 27 seconds.

Explanation:

In terms of ease of access and readability, both approaches are similar. However, it is evident from the time of execution that the with hashes is more efficient than the value of without hashes. This indicates that using hashes is more efficient.

Design a Python3 function to compare every prefix of a string X to every element of string Y, if there is a match, place it in a python set, sort and reversely sort the set, and return the sorted and reversely sorted sets.

Answers

Answer:

The function is as follows:

def compare_prefix(strX,strY):    

   prefix=set()

   for i in range(len(strX)):

       for j in range(i+1,len(strX)):

           chk =strX[i:j+1]

           if chk in strY:

               prefix.add(chk)

   

   sort_prefix = sorted(prefix)

   rev_sort_prefix = sorted(prefix,reverse=True)

   return(sort_prefix,rev_sort_prefix)

Explanation:

This defines the function

def compare_prefix(strX,strY):    

This creates an empty set, prefix

   prefix=set()

This iterates through each character in strX

   for i in range(len(strX)):

This iterates through every other character in strX

       for j in range(i+1,len(strX)):

This gets the prefix of strX by concatenating strings from i to j + 1

           chk =strX[i:j+1]

This checks if the prefix is in strY

           if chk in strY:

If yes, the string is added to set prefix

               prefix.add(chk)

   

This sorts prefix

   sort_prefix = sorted(prefix)

This reverses the sorted prefix

   rev_sort_prefix = sorted(prefix,reverse=True)

This returns the sorted and reversed prefix

   return(sort_prefix,rev_sort_prefix)

Which statement best describes Link State routing? Group of answer choices Each router builds a cost-weighted graph of the network of all the routers and the shortest links between them, based on information received from each router regarding only its nearest neighbors All of these Each router uses a HELLO packet to announce its presence to its neighbors Each router builds a table with the best distance between each router and the link to use, based on each router’s providing data on distances to all the routers in its routing table to its nearest neighbors

Answers

Answer:

Each router builds a cost-weighted graph of the network of all the routers and the shortest links between them, based on information received from each router regarding only its nearest neighbors.

Explanation:

A routing protocol can be defined as a set of defined rules or algorithms used by routers to determine the communication paths unto which data should be exchanged between the source router and destination or host device.

Additionally, in order for packets to be sent to a remote destination, these three parameters must be configured on a host.

I. Default gateway

II. IP address

III. Subnet mask

After a router successfully determines the destination network, the router checks the routing table for the resulting destination network number. If a match is found, the interface associated with the network number receives the packets. Else, the default gateway configured is used. Also, If there is no default gateway, the packet is dropped.

Basically, there are two (2) main categories of routing protocols used in packet switching networks and these includes;

1. Distance-vector routing.

2. Link state routing.

Link state routing refers to a complex routing technique in which each router learns about it's own neighborhood or directly connected networks (links) and shares the information with every other router present in the network.

Hence, the statement which best describes Link State routing is that, each router builds a cost-weighted graph of the network of all the routers and the shortest links between them, based on information received from each router regarding only its nearest neighbors. Some examples are intermediate system to intermediate system (IS-IS) and open shortest path first (OSPF).

There used to be a popular type of pulp book for younger readers. They were called "Choose Your Own Adventure" novels. The idea was pretty simple. You'd start reading and then a few pages into the book, there would be a plot development that required a choice. The book might describe that you've entered a spooky house and the door has locked behind you. It would then ask you if you want to try to exit by going through the kitchen or exploring upstairs. If you chose to go into the kitchen, you'd turn to page 200, if you chose to go upstairs, you'd turn to page 43. This would repeat maybe five or six times though the book. You could re-read it a few times and try different outcomes.
In this lab you are going to create a choose your own adventure application using navigation controllers. The introduction screen to your application will contain a few lines of text to set up a story and then leave the user with a choice. Below the text, you will present two buttons that correspond to the different choices.
For example, you might see the following text on the main screen:
You are walking down the street when a tiger runs up and takes your lunch and then runs away...
Do you want to chase the tiger or run away?
Chase
Run Away
The user must then tap one of the buttons. This will move the user to a new screen with a few more lines of the story and another choice and two more buttons. You will create three (3) turning points in your story. This means that your story will have eight (8) different possible outcomes and a total of 15 screens.
Requirements
The story must ask three (3) questions, no matter how the user answers the previous question. All the questions must be different and result in a different story text.
The story must have eight (8) possible different final outcomes.
The story must include a minimum of 15 screens in total.
Create content that is appropriate and not-offensive. We will share these and play them together.
For extra credit you can add an extra screen and use inputs to capture data from the user such as a name, favorite food, or lucky number and use this data in the story.

SMTP (Simple Mail Transfer Protocol) is the standard protocol for transferring mail between hosts over TCP. A TCP connection is set up between a user agent and a server program. The server listens on TCP port 25 for incoming connection requests. The user end of the connection is on a TCP port number above 1023. Suppose you wish to build a packet filter rule set allowing inbound and outbound SMTP traffic. You generate the following rule set:

Rule Direction Src Addr Dest Addr Protocol Dest Port Action
A In External Internal TCP 25 Permit
B Out Internal External TCP >1023 Permit
C Out Internal External TCP 25 Permit
D In External Internal TCP >1023 Permit
E Either Any Any Any Any Deny

Required:
Describe the effect of each rule.

Answers

Answer:

The five rules are described as follows:

Rule A permits the inbound Simple Mail Transfer Protocol (SMTP) connection.

Rule B permits the inbound Simple Mail Transfer Protocol (SMTP) connection.

Rule C permits the outbound Simple Mail Transfer Protocol (SMTP) connection.

Rule D permits the outbound Simple Mail Transfer Protocol (SMTP) connection.

Rule E does not perform any action. Thus it is when the action is denied.

Explanation:

Rule A allows information transfer of the incoming email from the external server to the internal remote server, thus this allows an inbound connection.

Rule B allows information transfer of the incoming email from the remote server to the external remote server, thus this allows an inbound connection.

Rule C allows information transfer of outgoing email from the external server to the internal remote server, thus this allows an outbound connection.

Rule D allows information transfer of the outgoing email from the remote server to the external remote server, thus this allows an outbound connection.

Rule E does not allow any action in either direction thus it is when action is denied.

Write a program that lets a maker of chips and salsa keep track of sales for five different types of salsa: mild, medium, sweet, hot, and zesty. The program should use two parallel 5-element arrays: an array of strings that holds the five salsa names and an array of integers that holds the number of jars sold during the past month for each salsa type. The salsa names should be stored using an initialization list at the time the name array is created. The program should prompt the user to enter the number of jars sold for each type. Once this sales data has been entered, the program should produce a report that displays sales for each salsa type, total sales, and the names of the highest selling and lowest selling products.

Answers

Answer:

The program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

 Scanner input = new Scanner(System.in);

 String [] salsa = {"Mild","Medium","Sweet","Hot","Zesty"};

 int [] number = new int[5];

 for(int i = 0;i<5;i++){

     System.out.print(salsa[i]+" number: ");

     number[i] = input.nextInt();

 }

 for(int i = 0;i<5;i++){

     System.out.println(salsa[i]+" : "+number[i]);

 }

 int smallest = number[0];  int highest = number[0];

 int count = 0;

 for(int i = 0;i<5;i++){

     if(smallest > number[i]){

         smallest = number[i];

         count = i;

     }

 }

 System.out.println("Smallest");

 System.out.println(salsa[count]+" : "+smallest);

    for(int i = 0;i<5;i++){

     if(highest < number[i]){

         highest = number[i];

         count = i;

     }

 }

 System.out.println("Highest");

 System.out.println(salsa[count]+" : "+highest);

}

}

Explanation:

This initializes the salsa names

 String [] salsa = {"Mild","Medium","Sweet","Hot","Zesty"};

This declares the array for the amount of salsa

 int [] number = new int[5];

This iterates through the 5 salsas and get input for the amount of each

 for(int i = 0;i<5;i++){

     System.out.print(salsa[i]+" number: ");

     number[i] = input.nextInt();

 }

This prints each salsa and the amount sold

 for(int i = 0;i<5;i++){

     System.out.println(salsa[i]+" : "+number[i]);

 }

This initializes smallest and largest to the first array element

 int smallest = number[0];  int highest = number[0];

This initializes the index of the highest or lowest to 0

 int count = 0;

The following iteration gets the smallest of the array elements

 for(int i = 0;i<5;i++){

     if(smallest > number[i]){

         smallest = number[i];

This gets the index of the smallest

         count = i;

     }

 }

This prints the smallest

 System.out.println("Smallest");

 System.out.println(salsa[count]+" : "+smallest);

The following iteration gets the largest of the array elements    

for(int i = 0;i<5;i++){

     if(highest < number[i]){

         highest = number[i];

This gets the index of the highest

         count = i;

     }

 }

This prints the highest

 System.out.println("Highest");

 System.out.println(salsa[count]+" : "+highest);
