Substitution mutations are not a type of mutation. Substitution mutations are not a type of mutation. No, substitution mutations are never harmful because they are silent. No, substitution mutations are never harmful because they are silent. It depends on whether the resulting amino acid of the codon has changed.

Answer 1

The correct response is: **It depends on whether the resulting amino acid of the codon has changed.**

Substitution mutations can be harmless, beneficial, or harmful depending on their effects on the protein produced. If the mutation results in a change in the amino acid sequence of a protein, it may affect the protein's function; if it results in a silent mutation (no change in the amino acid), it is generally neutral.
