Consider the observation that serine is the amino acid residue that can be replaced by another amino acid with the least effect

on protein structure and function. Which of the following is the most reasonable rationalization of this observation?
a. Serine is the amino acid residue that can be replaced with the least effect on protein structure and function.
b. Replacement of tryptophan causes the greatest effect on protein structure and function.
c. Replacements such as Lys→ and Leu → usually have very little effect on protein structure and function.

The question has incorrect option, however the question can be answered by the general explanation. On the basis of the general explanation the answer is as follows:

Answer:

The correct answer is - Serine has a small side chain that can fit in any relatively polar environment.

Explanation:

Serine is an amino acid that have a small side chain in comparison of other amino acid and can be replaced by another amino acid with very least effect on the structure and function of a particular protein as they can fit in any relatively polar environment.

Serine have hydroxyl group in their side chain. It is polar amino acid that can easily establish itself in any polar condition and cause least changes in protein structure and function.

Thus, the correct answer is - Serine has a small side chain that can fit in any relatively polar environment.

If a cell contains a set of duplicated chromosomes, does it contain any more genetic information than the cell before the chromo
zmey [24]

Answer:

No.

Explanation:

When the set of chromosomes are duplicated, it means the chromosomes will be double the number.

However the genetic information will not change. It will remain the same.

Duplication of chromosomes is usually occurs among the interphase stage of mitosis where chromosomes will duplicate to ensure the formation of two identical daughter cells.

In these cells there will be no addition or variation in genetic information.

Who discovered that dna was the genetic material or transforming factor that could convert nonvirulent r-type streptococcus pneu
KatRina [158]
Discovery
               In 1928 it was discovered by Frederick Griffith in an experiment generally known as transformation.

Experiment
                 
 In his experiment he considered two strains of <em>streptococus pneumonia,</em> one was R-type which was non-virulent and cause no disease in mice, other was virulent and S-type which cause disease and at last death of mice.
This experiment was comprised of four steps which are as follow:

 Step 1:
           First he injected living strain of S into mice, after sometime mouce died.

Step 2:
          He injected living strain of R into mice, the mice alive as he did not got any disease.

Step 3:
         He injected heat killed strain of S into mice and mice remain alive.

Step 4:
           He mixed living R strain with heat killed S strain and then inject into mice. As a result the mice died.

Conclusion:
                  It was found that genetic material from heat killed S stain were transferred to living R (non-virulent) strain, as a result R become virulent and cause the death of mice.

What happens when there is a high concentration of positive transcription factors but a low affinity for the positive transcript
Troyanec [42]

When there is a high concentration of positive transcription factors but a low affinity for the positive transcription factor

Transcription factors are proteins that regulate the transcription of genes—that is, their copying into RNA, on the way to making a protein.

Proteins called transcription factors, however, play a particularly central role in regulating transcription. These important proteins help determine which genes are active in each cell of your body.

<h3>How does transcription factors affect gene expression?</h3>

Under the influence of transcription factors, the various cells of the body can function differently though they have the same genome. Transcription factors attach to one or more series sites, which are called transcription element binding sites (TFBSs), binding to specific DNA sequences of the genes they control
