In which of the following scenarios is a silent mutation least likely?

Question

Quizplus · Accepted Answer

Silent mutations are changes in the DNA sequence that do not result in a change in the amino acid sequence of the protein. They are most likely to occur in exons, where the DNA sequence directly codes for proteins. Changes in the 5' UTR, 3' UTR, promoter, and introns do not directly alter the amino acid sequence of proteins, making a silent mutation least likely in these regions compared to an exon.
