How can a gene be damaged
WebDNA bases can be damaged by: (1) oxidative processes, (2) alkylation of bases, (3) base loss caused by the hydrolysis of bases, (4) bulky adduct formation, (5) DNA crosslinking, and (6) DNA strand breaks, including single and double stranded breaks. An overview of these types of damage are described below. WebThe p53 protein directs suicide of cell with DNA damage. Normally the p53 protein helps the cell destroy itself (cell suicide, or apoptosis) when its DNA becomes damaged (top row). This prevents the cell from going on to divide. But if the p53 gene has a mutation, then the p53 protein doesn’t work properly to help the cell commit suicide.
