D
Inversion
Verified step by step guidance
1
Understand the concept of a mutation: A mutation is a change in the DNA sequence that can affect genetic information.
Identify the types of mutations listed: Translocation, Deletion, Duplication, and Inversion.
Define each type of mutation: Translocation involves a segment of DNA breaking off and attaching to a different chromosome. Deletion is the loss of a DNA segment. Duplication is the repetition of a DNA segment. Inversion involves a segment of DNA breaking off, flipping, and reattaching in the reverse orientation.
Focus on the definition of Inversion: In an inversion mutation, a segment of DNA breaks, flips 180 degrees, and reattaches to the same chromosome, altering the sequence of genes.
Conclude that the mutation described in the problem, where a section of DNA breaks, flips, and reattaches, is an Inversion.
