Cisplatin-induced DNA damage activates replication checkpoint ... …
WebFeb 7, 2024 · A β-strand in the little finger (LF) domain of the protein provides a molecular splint that stabilises the newly-synthesized double-stranded DNA into a B-form structure, preventing CPD-induced duplex distortion and frameshift formation, which facilitates efficient and accurate Pol η-mediated bypass of thymine-thymine CPDs ( 40, 50, 51 ). WebDec 2, 2024 · Cisplatin, unlike transplatin, can bond to the same piece of DNA with two bonds to block DNA replication. This lack of replication can kill cancerous cells. The structure of transplatin makes it so that it can only bond at one site on DNA, which is not strong enough to stop DNA replication. Top Frederick Keith_4C Posts: 65 philip neame falklands
