________ do not produce any change in the amino acid sequence of a protein.

Question

Quizplus · Accepted Answer

Synonymous substitutions, also called silent mutations, do not result in any change in the amino acid sequence of a protein. This is because the genetic code is degenerate, meaning that multiple codons can code for the same amino acid. Therefore, a change in the third nucleotide of a codon may result in a different codon being used, but it will still code for the same amino acid. The other choices are not correct because transposable elements and highly accelerated regions can lead to changes in the DNA sequence, which can affect the amino acid sequence of a protein. Microsatellite loci are short repetitive sequences that do not code for proteins, and so they are also not relevant to changes in the amino acid sequence.
