which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?

KATRIN_1 [288]

An example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation is option B: replacement of a polar amino acid with another polar amino acid at the protein's surface.

A frequent and well-known example of a missense mutation is the blood condition sickle-cell anemia. Missense mutations exist in the DNA at a single location in sickle-cell anemia patients. A different amino acid is required in this missense mutation, which also alters the overall structure of the protein. Similarly, replacement of a polar amino acid by another polar Ami no acid at the protein's surface is a missense mutation causing change in a single site.

A neutral mutation is one whose fixation is unrelated to natural selection. Therefore, the independence of a mutation's fixation from natural selection can be used to define the selective neutrality of a mutation.

Complete question is:

Which example of a missense mutation in a protein-encoding gene would most likely be a neutral mutation?

a) Replacement of a polar amino acid with a nonpolar amino acid at the protein's outer surface

b) Replacement of a polar amino acid with another polar amino acid at the protein's surface

c) Replacement of a polar amino acid with another polar amino acid in the protein's interior

d) Replacement of a polar amino acid with a nonpolar amino acid in the protein's interior

Answer:

B- environmental factors do most of the “selecting.”

Explanation:

Natural selection is the environment that the organism lives in, and the process which that organism changes by.

Artificial selection is when humans intervene and create an organism that isn't suited for their specific environment, but rather for the humans own liking.

Think of breeding dogs to be smaller, or more fluffy and adorable. These are not traits to help them survive in where they original environment was.

Dna is used to tell people apart. What aspects of dna do you think make this possible?.

Fittoniya [83]

Answer:

DNA can be used to tell people apart because humans differ from each other based on either their DNA sequences or the lengths of repeated regions of DNA. Length difference are typically used in forensics and paternity testing.
