Question

many different types of mutations can occur within the body. an individual experiences a mutation that changes a base in a mrna strand, but during translation the mrna strand still creates the same protein. which type of mutation is responsible for the change in the mrna base? silent missense nonsense insertion

Explanation:

A silent mutation is a type of point mutation where a change in the DNA (and thus mRNA) base does not change the amino acid encoded, so the protein remains the same. A missense mutation changes the amino acid, a nonsense mutation creates a stop codon, and an insertion is a frameshift mutation that alters the reading frame. Since the mRNA still creates the same protein, it's a silent mutation.

Answer:

A. silent
