Question

What is the term for a very common type of DNA damage that stalls DNA replication and sometimes leads to chromosomal rearrangements?

A) Thymine dimerization
B) Base excision
C) Interstrand crosslink
D) DNA double-strand break

Answer 1

Thymine dimerization is a common type of DNA damage that stalls replication and can cause chromosomal rearrangements.

Step-by-step explanation:

The term for a very common type of DNA damage that stalls DNA replication and sometimes leads to chromosomal rearrangements is thymine dimerization. Thymine dimers are formed when adjacent pyrimidines (commonly thymines) on a DNA strand become covalently linked due to exposure to UV light.
