Qhov no txhais tau hais tias cov tshuaj tuaj yeem nres tus kab mob rov ua dua yam tsis muaj kev cuam tshuam loj npaum li cas cov hlwb ua cov nucleic acids ib txwm.
3. Cov kab mob puas tuaj yeem tiv thaiv kab mob GS-441524 hmoov? Yog tsis yog, dab tsi txwv qhov no tshwm sim?
Nws tseem muaj peev xwm ua tau rau cov kab mob los tiv thaiv cov nucleoside analogs, tab sis GS-441524 hmoov ua rau nws nyuaj heev rau qhov tshwm sim. Vim hais tias cov molecule muaj cov qauv uas zoo ib yam li tej yam ntuj tso adenosine, polymerase hloov pauv uas txwv tsis pub nws ntxiv feem ntau kuj nres cov enzyme los ntawm kev siv tej yam ntuj tso substrates. Qhov kev sib pauv no ua rau cov nqi qoj ib ce uas ua rau nws nyuaj rau nrhiav txoj hauv kev zoo. Kev hloov pauv feem ntau cuam tshuam rau kev ua haujlwm lossis kev ua haujlwm ntawm polymerase, uas txo qis tus kab mob lub peev xwm los luam nws tus kheej txawm tias nws tsuas yog qee qhov txo qis nws cov tshuaj tiv thaiv kab mob. Siv qhov peb paub los ntawm kev siv tshuaj kho mob, kev tawm tsam tshwm sim maj mam thiab ua tsis tiav, yog li kev kho mob ua haujlwm ntev dua.
