Kev sau ntawv siv ib qho ntawm ob qhov nthuav tawm DNA strands ua ib qho tus qauv ; txoj hlua no hu ua tus qauv txoj hlua. Cov khoom RNA yog ntxiv rau cov khoom tus qauv strand thiab yuav luag zoo tib yam rau lwm yam DNA strand, hu ua nontemplate (los yog coding) strand.

Yog li ntawd, tus qauv rau kev txhais lus yog dab tsi?

Kev txhais lus . Kev hloov pauv yog kev sib txuas ntawm RNA los ntawm DNA tus qauv qhov twg cov cai hauv DNA tau hloov mus rau hauv RNA code ntxiv. Kev txhais lus yog qhov kev sib txuas ntawm cov protein los ntawm mRNA tus qauv qhov twg cov cai hauv mRNA hloov mus rau hauv cov amino acid ib ntus hauv cov protein.

Secondly, dab tsi yog qhov kawg khoom ntawm transcription? Cov kawg khoom ntawm transcription yog RNA molecule. Li no, kev luam cov ntaub ntawv ntawm cov noob hauv cov genome rau hauv RNA tshwm sim thaum lub sijhawm kev sau ntawv . Peb hom tseem ceeb ntawm RNA tsim los ntawm kev sau ntawv yog mRNA, tRNA, thiab rRNA.

Yog li ntawd, dab tsi yog qhov txheej txheem ntawm transcription?

Kev sau ntawv yog cov txheej txheem los ntawm qhov uas cov ntaub ntawv nyob rau hauv ib tug strand ntawm DNA yog theej rau hauv ib tug tshiab molecule ntawm messenger RNA (mRNA). DNA muaj kev nyab xeeb thiab ruaj khov khaws cov khoom siv caj ces hauv cov nuclei ntawm cov hlwb raws li kev siv, lossis qauv.

Cov txheej txheem twg yog ib feem ntawm kev sau ntawv?

Kev sau ntawv yog cov txheej txheem uas DNA tau theej ( luam tawm ) mus rau mRNA, uas nqa cov ntaub ntawv xav tau rau kev tsim cov protein. Kev sau ntawv yuav tshwm sim nyob rau hauv ob kauj ruam dav. Ua ntej, ua ntej tus xa xov RNA yog tsim, nrog kev koom tes ntawm RNA polymerase enzymes.
