question 13 of 25
which type of mutation causes a protein to be synthesized with one incorrect amino acid?
a. frameshift
b. missense
c. silent
d. nonsense

Explanation:

A missense mutation changes a single nucleotide in DNA, leading to one incorrect amino acid in the protein. Frameshift mutations (A) disrupt the reading frame, often causing multiple amino - acid changes. Silent mutations (C) don't change the amino acid (due to codon degeneracy). Nonsense mutations (D) introduce a premature stop codon, truncating the protein. So, the mutation that causes one incorrect amino acid is a missense mutation.

Answer:

B. Missense
