5-Bromouracil CAS: 51-20-7 Theko ea moetsi

5-bromouracil ke analoge ea maiketsetso ea thymine, karolo ea DNA. Ha e le teng ka har'a DNA, 5-bromouracil e ka feta phetohong ea tautomeric, e leng se lebisang ho se sebetseng hantle le guanine nakong ea ho ikatisa ha DNA, e leng se ka fellang ka liphetoho. Thepa ena e entse hore 5-bromouracil e be molemo e le phetoho ea liphatsa tsa lefutso lipatlisisong tsa liphatsa tsa lefutso, haholo-holo bakeng sa ho ithuta sekhahla sa liphetoho le mekhoa ea phetoho. E boetse e sebelisitsoe ho batlisisa sebopeho le ts'ebetso ea nucleic acid, hammoho le lithutong tse amanang le tokiso le lits'ebetso tsa ho ikatisa ha DNA. Ho feta moo, 5-bromouracil e sebelisitsoe ho ithuta phetoho ea liphatsa tsa lefutso le polelo ea liphatsa tsa lefutso linthong tse fapaneng tse phelang.
