WebReactive oxygen species cause oxidative damage to several bacterial targets, including DNA (Imlay et al., 1988). As purine auxotrophs lack the ability to synthesize purine nucleotides and hence DNA and RNA, we hypothesized that the intramacrophage attenuation of purine auxotrophs might be due to their inability to repair DNA damage … WebMeaning of dna repair.

DNA repair is a collection of processes by which a cell identifies and corrects damage to the DNA molecules that encode its genome. In human cells, both normal metabolic activities and environmental factors such as radiation can cause DNA damage, resulting in tens of thousands of individual molecular lesions per cell per day. Many of these lesions cause structural damage to the DNA molecule and can alter or eliminate the cell's ability to transcribe the gene that the affected D… bmb fashion
