This article throws light upon the top seven DNA damage repair mechanisms. The top seven DNA damage repair mechanisms are: (1) Proofreading by DNA Polymerase (2) Excision Repairs (3) Spontaneous Repair by DNA Double Helix (4) Homologous and Non-homologous DNA Repair (5) SOS Repair (6) Mismatch Repair of Single-Base Mispairs and (7) Photo-reactivation UV-induced Pyrimidine Dimers. Mechanism # 1. Proofreading [...]

This article throws light upon the four causes DNA damage. The four types of factors that cause DNA damage are: (1) Hydrolysis (2) Deamination (3) Alkylation and (4) Oxidation. Cause # 1. Hydrolysis: DNA consists of long strands of sugar molecules called deoxyribose that are linked together by phosphate groups. Each sugar molecule carries one of the four natural DNA [...]
