Answer:
Viruses are not living things.
Answer: No.
Explanation:
Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply.
How could you tell whether a given sequence was DNA or mRNA?
Was it easier to decode messages written in DNA or in mRNA sequences?
Which cellular enzymes or machines are you imitating when you "transcribe" DNA into mRNA?
Which cellular enzymes or machines are you imitating when you "translate" mRNA into a chain of amino acids?
What else needs to happen in a eukaryotic cell between the processes of transcription and translation?
In step 5, how did different mutations affect the amino acid sequence that was encoded?
Explain why some single nucleotide mutations affect an amino acid sequence and some single nucleotide mutations do not.
Explain why nucleotide insertions and deletions affect the amino acid sequence so profoundly.
Why could your secret message include only 20 of the 26 letters of the alphabet?
Did you find that it was difficult to work with only these letters?
Answer:
1. You could tell whether a given sequence was DNA or mRNA because of Uracil and Thymine base differences in both
2. Answers may vary up to you, but messages are easier to decode written in DNA
3. You are imitating RNA polymerases.
4. You are imitating RNA polymerase once again
5. The RNA strand is delivered to start the process of translation; RNA>>Protien
6. Different mutations affect different amino acid sequences because they alter the code which makes it un-easy to decode the sequence
7. Some single nucleotide mutations affect an amino acid sequence depending on what mutation it is causing. Some single nucleotide mutations do not do this because they aren't as severe and they don't cause codons to mix up.
Answer:
1
ADNA sequences use the nucleotides A, T, G, and C, while mRNA sequences use the nucleotides A, U, G, and C.
B It was easier to decode the messages written in mRNA sequences because these sequences could be translated directly into the amino acid sequence.
2
A The cellular enzyme that carries out transcription is RNA polymerase.
B The cellular machine that carries out translation is the ribosome, which is composed of both rRNA and ribosomal proteins.
C In a eukaryotic cell, an mRNA transcript often has additional untranslated regions and a poly-A tail. A eukaryotic mRNA transcript would need to be transported from the nucleus to the cytoplasm before it could be translated.
3
A Some amino acids are encoded by several codons. If a single nucleotide mutation still encodes for the same amino acid, the resulting amino acid sequence would not be affected. This happens most often with nucleotides in the third position of a codon.
B If a single nucleotide mutation changes the amino acid encoded, the resulting amino acid sequence would be affected. This happens most often with nucleotides in the first and second positions of a codon.
C Nucleotide insertions and deletions cause frameshift mutations, which change the reading frame of translation and will encode completely different amino acids from that point forward.
4
A There are only 20 canonical amino acids, so the letters B, J, O, U, X, and Z are not used as one-letter codes.
B It was a little difficult to not use the letters B, J, O, U, X, and Z at first, but there are messages to write without these six letters.

Answer:Proteins are synthesised (made) by the ribosomes using messenger RNA transcribed from DNA in the nucleus.
Explanation:
In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled. The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.

b.
They all involve an interaction between living and nonliving elements.
C.
They are all part of the Earth system.
d.
All of the above.
Answer:
The carbon, nitrogen, and oxygen cycles are similar in the sense that:
They are all biogeochemical cycles.
They all involve an interaction between living and nonliving elements.
They are all part of the Earth system
BIOGEOCHEMICAL CYCLES:
Biogeochemical cycles has to do with the interrelationship of certain elements with their biological, chemical and geological environment.
The elements that are cycled in this processes are oxygen, nitrogen, carbon, phosphorus etc.
The cycling of these elements occur on Earth and they involve an interaction between living and nonliving components of the Earth.
Therefore, the carbon, nitrogen, and oxygen cycles are similar in the sense that:
They are all biogeochemical cycles.
They all involve an interaction between living and nonliving elements.
They are all part of the Earth system

Explain why clouds are more likely to form at higher elevations. (Use the terms relative humidity and dewpoint in your answer)
Answer & Explanation:
At higher elevations, water condenses from the air and produces clouds, which often blanket lofty peaks and completely obscure them. As the clouds get saturated with moisture, rain and snow fall. The precipitation, when combined with the strong winds, results in frequent stormy weather.

3.Which pathway depicts transport of a hydrophobic molecule?
Answer:
1. d.water comes "out of" or "exits" the reaction
2. a.energy goes "into" or "enters" the reaction
3. Path A
Explanation:
1) Peptide bond synthesis is dehydration reaction which means water is "dehydrated" meaning released when the reaction occurs.
2) Anytime we want to join things together we gotta use energy, these processes are anabolic reactions such as making sugars, proteins, lipids, in our cell. Since we are making protein here, we need to put energy into the reaction.
3) Path A is hydrophobic b/c they directly diffuse thru cell membrane to attach to intracellular receptor.
