Question

Quizplus · Accepted Answer

An inversion is a type of chromosomal rearrangement that occurs when a segment of DNA within a chromosome breaks off, rotates 180 degrees, and reattaches to the same chromosome in the reverse orientation. This results in a reorganization of the DNA sequence within the chromosome, but does not involve movement of genetic material between different chromosomes.
