Question

Quizplus · Accepted Answer

Inserting two bases into the coding region of a gene just after the start codon will alter the reading frame of the mRNA during translation, leading to a frameshift mutation. This type of mutation changes the grouping of the nucleotides into codons, which can significantly alter the amino acid sequence from that point forward.
