Answered

A point mutation changes a codon in an mRNA molecule. Will the mutation affect the polypeptide that forms? Why?
a. Yes. Each amino acid is specified by only one codon.
b. No. The structure of DNA, and not RNA, determines the polypeptide
c. Maybe. Some codons are translated into two or more amino acids.
d. Maybe. Some sets of codons are translated into the same amino acid.

Answer :

Answer:

The answer is either C or D because substitution mutations can change only one codon, and there are multiple codons that may code for the same amino acid. I would say the answer is D.
