Question

missense, nonsense, and silent mutations are examples of which type of mutation?
○ substitution
○ insertion
○ deletion
○ replication

Explanation:

Missense, nonsense, and silent mutations are types of point mutations that result from base - pair substitutions in DNA. Substitution mutations involve the replacement of one nucleotide with another. Insertion and deletion mutations are frameshift mutations (unless the insertion/deletion is a multiple of three nucleotides), and replication is the process of DNA copying, not a type of mutation that directly leads to missense, nonsense, or silent mutations. So the correct type of mutation for these examples is substitution.

Answer:

A. substitution
