Ua ke, cov txheej txheem hloov pauv thiab RNA polymerase tsim ib txoj hauv kev hu ua kev pib pib ua haujlwm. Qhov nyuaj no pib sau cov ntaub ntawv, thiab RNA polymerase pib mRNA synthesis los ntawm kev sib piv cov hauv paus rau qhov qub DNA strand.
Dab tsi enzyme complex yog lub luag haujlwm rau kev sau npe?
RNA polymerase yog ib qho enzyme uas yog lub luag haujlwm rau luam cov DNA sib lawv liag rau hauv RNA ib ntus, duyring tus txheej txheem ntawm transcription.
Dab tsi yog lub ntsiab enzyme complex koom nrog kev txhais lus?
Peptidyl transferase yog lub ntsiab enzyme siv hauv Kev Txhais Lus. Nws muaj nyob rau hauv cov ribosomes nrog ib qho kev ua haujlwm enzymatic uas catalyzes tsim ntawm covalent peptide daim ntawv cog lus ntawm cov amino acids uas nyob ib sab. Lub enzyme txoj haujlwm yog tsim peptide bonds ntawm cov amino acids uas nyob ib sab siv tRNAs thaum lub sij hawm txhais lus.
Dab tsi ua rau qhov kev pib hloov pauv hloov pauv?
A transcription-initiation complex muaj an RNA polymerase thiab ntau yam kev hloov pauv dav dav ua khi rau thaj tsam txhawb nqa.
3 kauj ruam tseem ceeb ntawm kev sau ntawv yog dab tsi?
Kev sau yuav ua rau peb kauj ruam: pib, elongation, thiab txiav tawm.
