D
Missense mutation
Verified step by step guidance
1
Understand the concept of a frameshift mutation: A frameshift mutation occurs when nucleotides are inserted into or deleted from the DNA sequence, causing a shift in the reading frame of the genetic code.
Identify the types of mutations: Common types include silent mutations, point mutations, missense mutations, and insertion or deletion mutations.
Recognize that silent mutations do not change the amino acid sequence and therefore do not cause a frameshift.
Understand that point mutations involve a change in a single nucleotide and typically do not cause a frameshift unless they result in an insertion or deletion.
Conclude that insertion or deletion mutations are the types that lead to a frameshift, as they alter the reading frame of the DNA sequence.
