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. Introduction of dna breaks and replication fork arrest. Much progress but many unresolved.

The ability of quinolone antibiotics to kill bacteria is a function of the stable interaction complex formed between drug bound topoisomerase enzyme and cleaved dna 4 mechanistically based on studies employing dna cleavage mutants of gyrase 23 and topoiv 24 that do not prevent quinolone binding as well as studies that have shown that.
