Answer 1

Answer #1

Base-excision repair.

in base excision repair, first, the damaged nitrogen base is removed by breaking the N glycosidic linkage by the enzyme N-glycosylase, then AP endonuclease removes the deoxyribosyl phosphate then polymerase beta fills the gap so the answer is Base-excision repair.

Can you please explain in detail DNA repair mechanisms from a biochemical point of view (direct reversal of damage- DNA methyltransferase, DNA photolyase, base excision repair- DNA glycosylase and nucleotide excision repair, as well as mismatch repair and SOS response and recombination repair) I really need your help. I will be forever grateful. And if I may ask you one thing if you copy from the internet please put the citations, or links. Thank you in advance!!!
