Ribosomal RNA (rRNA) koom nrog ib pawg ntawm cov proteins tsim ribosomes. Cov txheej txheem nyuaj no, uas lub cev txav mus raws ib qho mRNA molecule, catalyze lub sib dhos ntawm cov amino acids rau hauv protein ntau chains. Lawv kuj khi tRNAs thiab ntau yam khoom siv molecules tsim nyog rau protein ntau synthesis.

Tib neeg kuj nug, DNA thiab RNA ua cov protein li cas?

Ib qho protein yog ua los ntawm cov amino acids, daim ntawv no a txoj hlua. Thaum lub DNA tau sau rau hauv RNA , ib base DNA sib tham rau ib base RNA ,ib 1 rau 1 kev sib raug zoo tsis siv rau hauv kev txhais lus rau protein . Thaum lub sijhawm txhais lus no, 1 amino acid ntxiv rau tus protein ntau strand rau txhua 3 puag hauv lub RNA.

DNA puas ua RNA? Cov feem ntawm DNA uas tau muab sau rau hauv RNA hu ua "genes". Cells ua RNA lus nyob rau hauv ib tug txheej txheem zoo ib yam li cov replication ntawm DNA . Cov DNA strands yog rub sib nrug nyob rau hauv qhov chaw ntawm cov noob yuav transcribed, thiab enzymes tsim tus tub txib RNA los ntawm qhov sib lawv liag DNA bases siv lub hauv paus kev cai ua khub.

Yog li ntawd, hom RNA sib sau ua ke cov proteins li cas?

tRNA

Peb hom RNA yog dab tsi thiab lawv lub luag haujlwm hauv kev tsim cov protein ntau?

Peb hom RNA loj yog mRNA, los yog messenger RNA , uas yog cov ntawv luam ib ntus ntawm cov ntaub ntawv pom hauv DNA; rRNA, los yog ribosomal RNA , uas ua hauj lwm raws li structural Cheebtsam ntawm protein ntau - ua cov qauv hu ua ribosomes; thiab thaum kawg, tRNA, lossis hloov RNA , uas ferry amino acids rau ribosome yuav tsum tau sib sau ua ke
