Zuag qhia tag nrho Lub luag haujlwm ntawm tRNA hauv kev tsim cov protein yog txiav txim siab ib qho tshwj xeeb codon ntawm mRNA, siv nws cov anticodon, txhawm rau hloov cov amino acid tshwj xeeb mus rau qhov kawg ntawm cov saw hauv ribosome. Ntau tRNAs ua ke tsim los ntawm cov amino acid saw, thaum kawg tsim ib qho protein ntau rau tus thawj mRNA strand.

Dhau li ntawm qhov no, lub luag haujlwm ntawm tRNA yog dab tsi hauv cov lus nug ntawm cov protein synthesis?

Txhawm rau xa cov amino kom xa cov amino acids. Nqa cov amino acids thiab xa mus rau ribosome. tRNA xyuas kom meej cov amino acid raug xa tuaj ntawm lub sijhawm raug los ntawm kev sib piv cov tshuaj anticodons rau mRNA strands.

tRNA nyob qhov twg hauv protein synthesis? Cytoplasmic tRNAs muaj nyob rau hauv cov kua hauv cov hlwb (lub cytoplasm). Cov no tRNAs pab tsim cov proteins los ntawm cov noob nyob rau hauv DNA nyob rau hauv lub nucleus ntawm lub cell (nuclear DNA). Txawm hais tias feem ntau DNA yog nuclear, cellular qauv hu ua mitochondria muaj ib tug me me ntawm lawv tus kheej DNA, hu ua mitochondrial DNA.

Hauv qhov no, lub luag haujlwm ntawm tRNA yog dab tsi thaum lub sijhawm txhais lus?

hloov RNA / tRNA Hloov ribonucleic acid ( tRNA ) yog ib hom RNA molecule uas pab txiav txim siab tus tub txib RNA (mRNA) sib lawv liag rau hauv cov protein. tRNAs muaj nuj nqi ntawm qhov chaw tshwj xeeb hauv cov ribosome thaum lub sij hawm txhais lus , uas yog txheej txheem uas tsim cov protein los ntawm mRNA molecule.

Dab tsi yog lub luag haujlwm ntawm DNA thiab RNA hauv kev tsim cov protein?

DNA ua RNA ua Protein . Cov synthesis ntawm cov proteins tshwm sim nyob rau hauv ob theem ua ntu zus: Transcription thiab Translation. Transcription tshwm sim nyob rau hauv lub cell nucleus thiab siv lub hauv paus ib theem zuj zus ntawm DNA tsim mRNA. Lub mRNA nqa cov lus los ua ib qho tshwj xeeb protein ntau tawm mus rau cytoplasm qhov twg kev txhais lus tshwm sim.
