When a section of DNA is damaged and polymerization cannot proceed,_____ repair can reconstitute the damaged replication fork.

Question

Quizplus · Accepted Answer

Recombination repair can reconstitute the damaged replication fork by utilizing homologous recombination to replace the damaged DNA with an undamaged copy from the sister chromatid or homologous chromosome. Mismatch repair corrects errors in base pairing during replication, nucleotide excision repair repairs bulky DNA lesions caused by UV radiation or chemicals, photoreactivation repairs UV-induced DNA damage, and base excision repair removes damaged bases.
