Multiple Choice
In the context of types of mutations, which term best describes a mutation that has no effect on the amino acid sequence of the protein?
A
Frameshift mutation
B
Missense mutation
C
Nonsense mutation
D
Silent (synonymous) mutation
Verified step by step guidance1
Understand that mutations can affect the amino acid sequence of a protein in different ways depending on the type of mutation.
Recall that a frameshift mutation involves insertions or deletions that shift the reading frame, usually altering the entire amino acid sequence downstream.
Recognize that a missense mutation changes one codon so that it codes for a different amino acid, altering the protein sequence.
Know that a nonsense mutation changes a codon to a stop codon, leading to premature termination of the protein.
Identify that a silent (synonymous) mutation changes a codon to another codon that codes for the same amino acid, resulting in no change to the amino acid sequence.
