What is the Correct Order of Enzyme Activities Required for Nucleotide

Question

What is the correct order of enzyme activities required for nucleotide excision repair?
A)exonuclease,helicase,polymerase,ligase
B)exinuclease,helicase,polymerase,ligase
C)exonuclease,polymerase,ligase,helicase
D)exinuclease,polymerase,ligase,helicase
E)exonuclease,ligase,polymerase,helicase

Accepted Answer

Nucleotide excision repair involves the removal of a damaged DNA segment, which is initiated by an exinuclease that recognizes and excises the damaged strand. Helicase then unwinds the DNA, polymerase fills in the gap with new nucleotides, and ligase seals the strand.
