Question

The diagram shows a series of codons in an mRNA molecule before and after a genetic mutation. The mutation has caused an

adenine nucleotide base, rather than uracil, to be used to assemble a protein Despite the change, the sequence of amino acids in
the protein has not changed. Which term best classifies the genetic mutation?

Answer 1

This genetic mutation is called Substitution because adenine substituted uracil, and it is silent because the amino acid did not change.
