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?
A mutable object hloov tau tom qab nws tsim, thiab ib yam khoom hloov tsis tau. Uas tau hais tias, yog tias koj tab tom txiav txim siab koj tus kheej hauv chav kawm, koj tuaj yeem ua rau nws cov khoom hloov tsis tau los ntawm kev ua txhua qhov kawg thiab ntiag tug.
Kev hloov pauv hloov pauv yog qhov tib lub cev tshwm sim raws li kev hloov pauv ntawm lub zog ntxiv. Nyob rau hauv ob qho tib si, cov hlau quab yuam yog pauv mus rau lub pob zeb los ntawm kev sib zog ua haujlwm uas tau qhib los ntawm cov ntawv hlais ntawm qhov sib cuam tshuam .
