Nyob rau hauv molecular biology thiab noob caj noob ces, transcriptional regulation yog cov txhais tau tias los ntawm lub cell tswj kev hloov ntawm DNA rau RNA, yog li orchestrating noob kev ua si.
Tus tswj hwm kev hloov pauv ua dab tsi?
Cov kev cai raws li kev cai nruj nruj thiab tshwj xeeb los ntawm cov neeg tswj hwm kev hloov pauv, cov proteins uas tuaj yeem paub txog DNA ntu thiab khi rau lawv. Kev khi ntawm cov proteins no rau DNA tuaj yeem tswj cov ntawv sau los ntawm kev tiv thaiv lossis nce kev sau los ntawm ib tus neeg txhawb nqa
Cov kev tswj hwm kev sau ntawv ua haujlwm li cas?
Cov ntsiab lus hloov pauv yog cov proteins uas muaj cov thawj coj uas khi rau DNA ntawm kev txhawb nqa lossis txhim kho thaj chaw ntawm cov noob tshwj xeeb. … Lawv feem ntau ua li ntawd los ntawm ua rau cov neeg txhawb lossis txhawb nqa kom qhib lossis txwv tsis pub hloov pauv ntawm cov noob tshwj xeeb.
Yuav ua li cas tswj cov txheej txheem transcription?
Ua ntej, kev hloov pauv yog tswj hwm los ntawm kev txwv tus nqi ntawm mRNA uas yog tsim los ntawm cov noob tshwj xeeb. Qib thib ob ntawm kev tswj hwm yog los ntawm cov xwm txheej tom qab kev hloov pauv uas tswj cov kev txhais ntawm mRNA rau hauv cov protein. Txawm tias tom qab tsim cov protein, cov kev hloov pauv tom qab tuaj yeem cuam tshuam nws txoj haujlwm.
