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.

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

1. Describe the structure and function of each of the three types of RNA.
Ket [755]

Answer:

1.

mRNA - Messenger RNA: Encodes amino acid sequence of a polypeptide.

tRNA - Transfer RNA: Brings amino acids to ribosomes during translation.

rRNA - Ribosomal RNA: With ribosomal proteins, makes up the ribosomes, the organelles that translate the mRNA.

2.

Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.

3.

During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins. Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein.
