Hom RNA uas muaj cov ntaub ntawv los ua ib qho protein ntau hu ua messenger RNA (mRNA) vim nws nqa cov ntaub ntawv, los yog lus, los ntawm lub DNA tawm ntawm lub nucleus mus rau hauv cytoplasm. Los ntawm cov txheej txheem ntawm kev sau thiab txhais lus, cov ntaub ntawv los ntawm cov noob yog siv los ua cov proteins.

Tsuas yog li ntawd, DNA ncaj qha cov protein synthesis ntawm sab hauv lub nucleus li cas?

DNA ncaj qha protein synthesis los ntawm thickening thiab ces unzipping thiab ces muab theej mus rau messenger RNA thiab ces muab tso rau ribosomes thiab ces muab ua ke nrog cov khub nucleotide thiab ces siv los tsim cov amino acid thiab ces cov no. yog thauj sab nraud ntawm lub cell.

Yuav ua li cas cov proteins yog synthesized raws li cov lus qhia DNA? Nyob rau hauv thawj kauj ruam, transcription, lub DNA code yog hloov dua siab tshiab rau hauv RNA code. Ib tug molecule ntawm tub txib RNA uas yog complementary rau ib tug tshwj xeeb noob yog ua ke nyob rau hauv ib txoj kev zoo ib yam li DNA rov ua dua. Lub molecule ntawm mRNA muab cov cai rau ua ke ib protein ntau.

Qhov thib ob, lub luag haujlwm ntawm DNA yog dab tsi hauv kev tsim cov protein?

DNA ua haujlwm los ntawm coding rau lub synthesis ntawm cov proteins . Cov DNA (deoxyribonucleic acid) muaj nyob rau hauv lub nucleus ntawm lub cell, tsis tau protein synthesis tshwm sim sab nraum lub nucleus ntawm ribosomes hauv cytoplasm. Hloov RNA (tRNA) coj cov amino acids rau hauv txoj hauj lwm ntawm ribosome thaum lub sij hawm tsim kho ntawm a protein ntau.

Yuav ua li cas tshwm sim thaum lub sij hawm synthesis protein?

protein synthesis tshwm sim nyob rau hauv cellular qauv hu ua ribosomes, pom sab nraum lub nucleus. Cov txheej txheem los ntawm cov ntaub ntawv genetic hloov los ntawm cov nucleus mus rau ribosomes hu ua transcription. Thaum transcription, ib txoj hlua ntawm ribonucleic acid (RNA) yog ua ke.
