HELP ASAPPP Why can insertions and deletions affect more than just the codon(s) that they directly change? Hint: Why are they called frame-shift mutations?
Insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions, and deletions are usually more harmful than a substitution in which only a single amino acid is altered.
