Cov central dogma yog lub moj khaum los piav qhia txog qhov ntws ntawm cov ntaub ntawv caj ces los ntawm DNA rau RNA rau protein ntau . Thaum cov amino acids koom ua ke los ua ib qho protein ntau molecule, npe protein synthesis . Txhua protein ntau muaj nws tus kheej cov lus qhia, uas yog encoded nyob rau hauv seem ntawm DNA, hu ua noob.

Kuj paub yog, dab tsi yog lub hauv paus dogma?

Cov central dogma ntawm molecular biology piav txog cov txheej txheem ob-kauj ruam, kev hloov pauv thiab kev txhais lus, uas cov ntaub ntawv hauv cov noob ntws mus rau hauv cov protein: DNA → RNA → protein. Kev hloov pauv yog kev sib txuas ntawm RNA daim qauv ntawm ib ntu ntawm DNA. RNA yog tsim los ntawm enzyme RNA polymerase.

Ib tug kuj yuav nug, vim li cas lub hauv paus dogma tseem ceeb? Hauv kev xaus, lub qhov tseem ceeb ntawm central dogma rau niaj hnub biology yog tias tsis muaj cov txheej txheem no rov ua dua ntawm hom yuav tsis tshwm sim raws li cov ntaub ntawv caj ces yuav tsis tuaj yeem khaws cia thiab tsim cov proteins uas tseem ceeb hauv cov txheej txheem biochemical.

Cov lus nug tseem yog, dab tsi yog 3 ntu ntawm lub hauv paus dogma?

Replication, Transcription, thiab Translation yog peb lub ntsiab cov txheej txheem siv los ntawm txhua lub hlwb los tuav lawv cov ntaub ntawv caj ces thiab hloov cov ntaub ntawv caj ces hauv DNA rau hauv cov khoom lag luam, uas yog RNAs lossis cov protein, nyob ntawm cov noob.

Central dogma txhais li cas?

Cov Central Dogma ntawm Molecular Biology hais tias DNA ua RNA ua cov proteins (Daim duab 1). Daim duab 1 | Cov Central Dogma ntawm Molecular Biology: DNA ua RNA ua cov proteins. Cov txheej txheem uas DNA tau theej rau RNA yog hu ua transcription, thiab qhov uas RNA siv los tsim cov proteins hu ua txhais lus.
