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.

What tools do field study scientists use and what tools do laboratory scientists?
pochemuha

Answer:

Explanation:

Each of these types of scientists focus on different research studies and therefore needs different tools. Field Scientists' studies mainly revolve around observations which they, therefore, need only a pen and paper, this may sometimes change when they need bigger machinery to make a certain event occur, but this machinery is dependent on the type of research. On the other hand laboratory, scientists work with different specimens within the lab and tend to use tools such as Bunsen burner, beakers, reagent bottles, petri dishes, and microscopes.

Imagine a scenario where Barr bodies are not due to random inactivation, but rather, the silencing is due to paternal imprinting
artcher [175]

Answer:

<h2>If Barr bodies are not due to random inactivation, but rather, the silencing is due to paternal imprinting  then the frequency of men and women differs. </h2>

Explanation:

Red-green color  blindness: color blindness is an X-linked recessive disorder. The male having this disease will transmit his X chromosome (with the mutation) to his daughter, who will then be a carrier of the disease.  

If Barr bodies are not due to random inactivation, but rather, the silencing is due to paternal imprinting  then the frequency of men and women differs.

Male inherit its X chromosome only from mother and no X chromosome from father, having one Y chromosome but female receive one X chromosome from father and one from mother, having no Y chromosome, So if the paternal allele is silenced then the males are no affected.

What does random mean and how does it apply to genetics?
Darya [45]
The simplest answer would be to look at a punnet square. it gives you the random chance that a trait gets passed on to offspring. it's made off probability of dominant and recessive genes. But it's random in the end.
