Question

Chromosomal aberration in which two breaks occur in a chromosome and the intercalary segment reunites in a reverse order is categorised as:

• A. Duplication
• B. Translocation
• C. Inversion
• D. Segmental duplication

Hint:

Inversions can affect gene function if they disrupt a gene at one of the breakpoints or change the expression of a gene near the breakpoints.

Answer 1

The Correct Option is C

An inversion is a chromosomal aberration where a segment of a chromosome is reversed end to end.This occurs when a chromosome undergoes breakage and the resulting pieces rejoin in a reversed order.
