Question

Difference between nucleotide excision repair and base excision repair

Answer 1

Base excision repair (BER) is a DNA repair system occurs in cells.
Nucleotide excision repair (NER) is another type of DNA repair system found in cells.
BER repairs damages to small DNA adducts. NER repair large DNA adducts
BER recognizes the damages which do not cause significant distortions to the DNA helix. NER recognizes the damages which cause significant distortions to the DNA helix.
