Answer:
A.Base pair change results in a premature stop codon; protein is nonfunctional.
Explanation:
Mutation, generally, refers to any change that occurs to the genetic sequence of a DNA. It can occur in different forms, hence, has different types. One particular type is the base pair substitution mutation, which involves the replacement of one or more nucleotide base by another in a sequence.
Base pair substitution can either result in one of the following namely: silent, missense, and nonsense. In NONSENSE mutation, the replacement of bases in the sequence causes the translation process to stop because a STOP CODON is prematurely encountered. Hence, the protein is non-functional.
Which conclusion about the growth of new bacterial cells does the experiment support?
O Heat helps bacterial cells grow new bacterial cells faster.
New bacterial cells can only arise from preexisting bacterial cells.
The amount of available nutrients impacts the growth of new bacterial cells.
Growth of new bacterial cells depends only on the presence of nutrients.
Answer: New bacterial cells can only arise from preexisting bacterial cells.
Explanation:
Option A is wrong because when heat was applied, there was no new bacterial growth. Most likely because the heat killed the bacteria cells. Option C is also wrong as well the third trial had nutrients but no new bacteria cells grew.
Option D is wrong because in Trial 1, there were nutrients and yet no new cells were formed. This means that growth of new cells depends on more than nutrients alone.
This leaves option B as the correct answer which is proven by the lack of growth of new cells when there were no pre-existing ones in trial 3.

Goggles or appropriate safety glasses protect the eyes from:
a. chemical splashes
b. fumes of preservatives used on anatomy specimens
c. UV exposure when using UV radiation in the laboratory
d. burns from the hot plate or Bunsen burner
Answer:
A) chemical splashes
C)UV exposure when using UV radiation in the laboratory
Explanation:
Goggles as well as safety glasses can be regarded as a form of protective eyewear which helps to enclose and protect every area of the eyes to prevent particulates, chemicals as well as water from striking the eyes in the laboratory or in the field. Eyewear is used to prevent chemical splash during experiment, it can prevent exposure of UV radiation from entering the eye in the laboratory.
In order to protect our eyes using
Goggles or appropriate safety glasses, we must take this into consideration.
✓protective eyewear must be put on when required
✓ check the goggles to ensure its in good condition before using it and after using it.
✓ make sure the eyewear is fitted properly.

How much energy is gained during melting
Answer:
Explanation:
During melting, energy goes exclusively to changing the phase of a substance; it does not go into changing the temperature of a substance. Hence melting is an isothermal process because a substance stays at the same temperature.

You plan to clone a guide RNA sequence into the pML104 plasmid because you want to engineer the construct in bacteria and later express it in yeast. Unfortunately, your lab does not have any available pML104. Your friend in the lab next door lets you borrow a related plasmid pML107, and you quickly start your experiment. Will it work? Briefly explain.
Answer:
Yes, the experiment will work.
Explanation:
The reason behind this is that plasmids are well known to be DNA vector carriers. These plasmids have the ability to bring about changes in DNA fragments into various microorganisms and reveal them. The two plasmids compose of the same genomic marker such as the antibiotic resistance gene found in URA3. However, plasmids are most commonly found in bacteria, but also in eukaryotic cells. Oftentimes, the gene composition in the plasmids enhances the bacteria with a vantage edge such as antibiotic resistance.
Hence, it is obvious that in both, the molecular regulation in terms of expression of genes is alike in properties. Similarly, the numbers of copies and molecular weight are also the same.
We can thereby conclude that, provided that there is a proper restriction site, another host that is up to standard for plasmid can be replaced for each other.

How do you think an environment and weather of a country can affect the population and people of a region
Answer:
Greatly affect the population.
Explanation:
Environment and weather of a country greatly affect the population and people of a region because good environment with all resources and suitable weather attract people of other regions toward itself. If the location has plenty of water, vegetation, flat geography and food etc, the people settled in this location and increase occur in population whereas if the area doesn't have any natural resources so people migrate from that area.

Explanation:
Human growth hormone (HGH) is necessary for growth during human adolescence. Pituitary dwarfism is a condition that results from the inability of a person to produce HGH. Luckily, the human gene for HGH can be inserted into E. coli bacteria, which are able to make our HGH. The resulting HGH is used by people who are unable to make their own. What property about hereditary information makes this possible
Answer:
The correct answer is - DNA is a genetic language that is common and uses by every organism including humans and bacteria.
Explanation:
DNA is the unit of heredity and present in almost every living organism, it carries the genetic information and transfer from generation to generations. In this process of transfer of the genetic information, there are two processes transcription and translation helps to produce protein.
The ability to produce proteins with the help of DNA for the particular function as said in question which is HGH production. Correcting the abnormality of not able to produce HGH, to produce the normal protein with the help of putting human genes into Bacteria as DNA is universal genetic language.
Explain why an mRNA transcribed from the template strand of the SIRT3 gene in normal stomach ( NS ) cells is translated to produce a SIRT3 protein of correct sequence, but if an mRNA were transcribed from the nontemplate strand of the SIRT3 gene in these cells, it would not produce a SIRT3 protein of correct sequence.
Answer:
Explanation:
The double-stranded DNA molecule has the potential to store genetic information in either strand, although in most organisms only one strand is used to encode any particular gene.
The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).
Thus, genetic information is expressed by transcription of the non-coding (template) strand of DNA, which produces an mRNA molecule that has the same sequence as the coding strand of DNA. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.

The measured distance between genes D and E in a two point test cross is 50 map units. What could this mean in physical terms
Answer:
Genes that express 50% of recombination frequency or more are not linked genes. They might be in different chromosomes or located in the same one, but too far from each other.
Explanation:
Genes are physically located in chromosomes. Many genes segregate independently after crossing-over because they are located far away from each other. But some other genes are too close, and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.
We need to know that 1% of recombination frequency = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
When the recombination frequency is inferior to 50%, genes are linked. If it is equal or superior, they are not linked. Genes are located far enough from each other to assort independently.
Genes that express 50% of recombination frequency or more are not linked genes. They might be in different chromosomes or located in the same one, but too far from each other.

Which of the following is TRUE about alleles? Which of the following is TRUE about alleles? The phenotype of the individual will always indicate with certainty the alleles of the individual. An individual will only carry one version of an allele. Alleles come in two forms, the good form and the bad form. Individuals carry both forms of each allele. An allele is a variant form of a gene.
Answer:
An allele is a variant form of a gene.
The phenotype of the individual will always indicate with certainty the alleles of the individual
Explanation:
An allele is the alternate form of a gene example is allele A, allele a
While writing the genotype of an individual the allele is always seen, it usually written in pairs example is AA , Aa, aa, SS
The phenotype of an individual will reveal the allele such person have example is an individual with the sickle cell having allele s through the appearance of such individual one could know if such person posses the allele.

Membrane potential is present only in nerve cells.
Describe the immediate effect of the neurotoxin on the number of action potentials in a postsynaptic neuron. Predict whether the maximum membrane potential of the postsynaptic neuron will increase, decrease, or stay the same.
Answer:
Inhibit control over ions.
Explanation:
The immediate effect of the neurotoxin on the postsynaptic neuron is to inhibit control over ion concentrations across the cell membrane. The neurotoxin blocks nervous transmission at synapses which prevents the vesicles containing the neurotransmitter from fusing with the presynaptic membrane so the information does not transfer from one neuron to another and as a result the body is present at constant relaxation mode. The membrane potential of postsynaptic neuron will decrease due to neurotoxin.

A guinea pig with giant muscles is bred with a guinea pig with regular muscles. If muscle size in guinea pigs is INCOMPLETE dominance would these guinea pigs be able to produce a weak muscle guinea pig?
Answer:
Yes, they would be able to produce weak muscled guinea pigs
Please see details below
Explanation:
This question involves a single gene coding for muscle size in guinea pigs. The allele for giant muscles (G) is incompletely dominant over the allele for regular muscles (R). This means that a third intermediate phenotype (weak muscles) is produced in a heterozygous state.
According to this question, a guinea pig with giant muscles (GG) is bred with a guinea pig with regular muscles (RR). The following gametes will be produced by each parent:
GG - G and G
RR - R and R
Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:
GR, GR, GR, and GR
This shows that all the offsprings (100%) have weak muscles, hence, YES is the answer to this question.
