Transcription yog txheej txheem ntawm luam cov ntaub ntawv ntawm dna mus rau Rna, yog li thaum transcription RNA raug tsim tawm.
Yuav ua li cas thaum transcription thiab nws tsim dab tsi?
Kev txhais lus yog cov txheej txheem uas cov noob DNA tau luam tawm (tshaj tawm) los ua RNA moleculeRNA polymerase yog lub ntsiab lus enzyme. … RNA polymerase siv ib qho ntawm cov DNA strands (cov qauv strand) ua tus qauv los ua ib qho tshiab, ntxiv RNA molecule.
Yuav ua li cas thaum txhais?
Cov molecule uas tau los ntawm kev txhais lus yog protein -- lossis ntau dua, kev txhais lus ua rau luv luv ntawm cov amino acids hu ua peptides uas tau stitched ua ke thiab ua cov proteins. Hloov RNA khi rau cov amino acids thiab rub lawv mus rau tus tub txib RNA strand ntawm ribosome. …
Dab tsi yog tsim thaum lub sijhawm hloov RNA polymerase?
Lub ntsiab enzyme koom nrog hauv kev sau ntawv yog RNA polymerase, uas siv cov qauv DNA ib leeg los ua ke ib qho sib ntxiv ntawm RNA Tshwj xeeb, RNA polymerase tsim RNA strand hauv 5' mus rau 3' kev taw qhia, ntxiv txhua nucleotide tshiab rau 3' kawg ntawm txoj hlua.
5 kauj ruam ntawm kev txhais lus yog dab tsi?
