RNA synthesis (tseem hu ua transcription) yog kev tsim tawm ib RNA molecule los ntawm nucleotides adenine (A), cytosine (C), guanine (G), los yog uracil (U). Cov nucleotides koom ua ke los ntawm enzyme RNA Polymerase (pom ntsuab hauv qab).

Tsis tas li ntawd, dab tsi yog txheej txheem ntawm synthesizing RNA?

Transcription yog txheej txheem ntawm synthesizing ribonucleic acid ( RNA ). Synthesis tshwm sim nyob rau hauv lub nucleus ntawm eukaryotic hlwb los yog nyob rau hauv lub cytoplasm ntawm prokaryotes thiab converts cov noob caj noob ces los ntawm ib tug noob nyob rau hauv deoxyribonucleic acid (DNA) mus rau ib tug strand ntawm RNA uas ces directs protein synthesis.

Tom qab, lo lus nug yog, puas RNA synthesis xav tau DNA? RNA yog feem ntau ua ke los ntawm DNA . Cov synthesis feem ntau xav tau ib lossis ntau cov enzymes nyiam RNA polymerase . Cov DNA txoj hlua yog siv raws li ib tug template los yog phau ntawv qhia uas lub RNA yog tsim. Txij li thaum RNA tsim cov proteins, qhov no yog txoj kev DNA tuav cov ntawv xiav rau tag nrho cov proteins tsis tawm hauv lub nucleus.

Raws li txoj cai, dab tsi enzyme koom nrog hauv RNA synthesis?

Lub enzyme uas yog lub luag haujlwm rau RNA synthesis yog hu ua RNA polymerase. Nws yog ib DNA nyob ntawm RNA polymerase piv txwv li nws siv DNA raws li ib tug template rau synthesize RNA.

Lub luag haujlwm ntawm mRNA yog dab tsi?

Qhov tseem ceeb kev ua haujlwm ntawm mRNA yog los ua tus neeg nruab nrab ntawm cov ntaub ntawv caj ces hauv DNA thiab cov amino acid sib lawv liag ntawm cov protein. mRNA muaj cov codons uas yog ua tiav rau cov kab ke ntawm nucleotides ntawm cov qauv DNA thiab qhia kev tsim cov amino acids los ntawm kev ua ntawm ribosomes thiab tRNA.
