dna repair mechanisms are intricate cellular processes that safeguard the integrity of the genome by detecting and repairing damaged or mismatched nucleotides in dna. these mechanisms are crucial in preventing the accumulation of mutations and ensuring the accurate transmission of genetic information during cell division.
there are several dna repair pathways, each specialized in correcting specific types of dna damage, such as base - excision repair, nucleotide excision repair, and mismatch repair. these pathways involve various enzymes that recognize, excise, and replace damaged or incorrectly paired nucleotides, restoring the dna sequence to its original state.
choose the correct answer.
what is one type of dna repair mechanism?
frameshifts
mismatch repair
deletions

Explanation:

DNA repair mechanisms correct damaged or incorrect nucleotides. Frameshifts and deletions are types of mutations, not repair mechanisms. Mismatch repair is a well - known DNA repair pathway that fixes incorrectly paired nucleotides.

Answer:

mismatch repair
