Topoisomerase Enzymes Enzymes hu ua topoisomerasestawm tsam qhov no los ntawm kev qhia qhov tsis zoo supercoils rau hauv DNA txhawm rau txhawm rau txo qhov kev ntxhov siab hauv helical molecule thaum rov ua dua. Muaj plaub lub npe hu ua topoisomerase enzymes pom hauv E.
Yuav ua li cas protein relaxes supercoils los ntawm nicking DNA quizlet?
Cov kauj ruam hauv DNA replication nyob rau hauv uas ob replication forks tsiv nyob rau hauv opposite lus qhia yuav ua tau raws li: C) txiav. Cov pab pawg enzymes tuaj yeem so supercoils hauv DNA hu ua: C) topoisomerases.
Dab tsi so supercoiling hauv DNA?
DNA gyrase relaxes DNA supercoiled los ntawm kev txiav nws, tso cai rau kev sib hloov tshwm sim, thiab tom qab ntawd rov txuas nws. Fluoroquinolones khi rau thiab inhibit DNA gyrase (tseem hu ua topoisomerase II) thiab topoisomerase IV.
Yuav ua li cas cov protein txo cov supercoiling?
Cov kab mob no feem ntau muaj topoisomerase I, ob hom IIA topoisomerases, thiab ob hom III enzymes. Topoisomerase Kuv pab nrog replication diav rawg txav thiab relaxes supercoils txuam nrog transcription.
Dab tsi enzyme relaxes supercoils?
DNA gyrase relaxes DNA supercoiled los ntawm kev txiav nws, tso cai rau kev sib hloov tshwm sim, thiab tom qab ntawd rov txuas nws. Fluoroquinolones khi rau thiab inhibit DNA gyrase (tseem hu ua topoisomerase II) thiab topoisomerase IV.
