Gene qhia yog cov txheej txheem uas cov lus qhia hauv peb DNA tau hloov mus rau hauv cov khoom siv, xws li cov protein. Gene qhia yog cov txheej txheem nruj nruj uas tso cai rau lub cell los teb rau nws qhov chaw hloov pauv.
Tom qab ntawd, ib tug kuj yuav nug, nws txhais li cas thaum lub noob tau qhib?
Txhua cell qhia, los yog tig rau , tsuas yog ib feem ntawm nws noob . Tus so ntawm noob raug tsim txom, los yog tig tawm. Cov txheej txheem ntawm tig noob on thiab off yog lub npe hu ua noob kev cai. Cov proteins no khi rau cov cheeb tsam tswj hwm ntawm a noob thiab nce lossis txo qib ntawm kev sau ntawv.
Ib tug kuj yuav nug, dab tsi yog gene qhia hauv cov ntsiab lus yooj yim? Gene qhia yog cov txheej txheem uas cov ntaub ntawv keeb kwm yav dhau los hauv a noob , qhov sib lawv liag ntawm DNA puag khub, yog ua rau ua haujlwm noob khoom, zoo li protein ntau los yog RNA. Lub tswv yim tseem ceeb yog DNA tau hloov mus rau RNA, uas tom qab ntawd muab txhais ua cov protein.
Tib neeg kuj nug, dab tsi tuaj yeem tig cov noob rau lossis tawm?
Cov noob kev tswj hwm cov protein tso cai rau tus neeg noob ntawm lub cev mus rau tig pe lub tawm tshwj xeeb. Txawv kev xaiv ntawm noob kev tswj hwm cov protein muaj nyob hauv ntau hom cell thiab yog li coj cov qauv ntawm noob nthuav qhia uas muab txhua hom cell nws cov yam ntxwv tshwj xeeb.
Nws txhais li cas thaum peb hais tias cov noob raug muab tua quizlet?
A) Cov noob yog tam sim no qhib. B) Cov noob tsis tuaj yeem sau thiab txhais ua cov protein.
