DNA Repair Mechanisms Occur

Question

DNA repair mechanisms occur
A) only in prokaryotes.
B) only in eukaryotes.
C) in both eukaryotes and prokaryotes.
D) in neither eukaryotes nor prokaryotes.
E) None of the answer choices is correct.

Accepted Answer

DNA repair mechanisms are present in both eukaryotes and prokaryotes. These mechanisms are essential for maintaining the integrity of genetic material and promoting the survival of organisms. They can correct different types of damage to DNA, including chemical modifications, radiation damage, and errors in replication. Examples of DNA repair mechanisms found in both prokaryotes and eukaryotes include base excision repair, nucleotide excision repair, and mismatch repair.
