which is a point mutation and not a frameshift mutation? mutagen insertion deletion silent
Answer
Answer:
D. silent
Brief Explanations:
A point - mutation is a change in a single nucleotide. Silent mutations are a type of point - mutation where the change in the nucleotide sequence does not result in a change in the amino - acid sequence of the protein. Insertions and deletions (other than multiples of 3) are frameshift mutations. A mutagen is an agent that causes mutations, not a type of mutation.
