Kev sau ntawv. Transcription yog tus txheej txheem uas DNA yog theej (transcribed) rau mRNA, uas nqa cov ntaub ntawv xav tau rau protein synthesis . Kev hloov pauv yuav tshwm sim hauv ob kauj ruam dav. Ua ntej, tus xa xov xwm ua ntej RNA yog tsim, nrog kev koom tes ntawm RNA polymerase cov enzymes.

Ntxiv mus, DNA replication thiab protein synthesis yog dab tsi?

Protein synthesis thiab DNA replication yog ob tug mechanisms qhov twg ob-stranded DNA molecules muaj kev koom tes. thawj tus qauv. Protein synthesis yog cov synthesis ntawm ib qho amino acid sequence ntawm a protein ntau . DNA replication yog cov. synthesis ntawm ib qho tshiab DNA molecule los ntawm ib qho uas twb muaj lawm DNA molecule.

Tom qab ntawd, lo lus nug yog, dab tsi zoo sib xws hauv cov txheej txheem ntawm DNA replication thiab protein synthesis? Protein synthesis ua cov proteins , thaum DNA replication ua DNA . DNA replication tshwm sim nyob rau hauv lub nucleus thiab tsim ob zoo tib yam pawg DNA . Protein syntheses tsim mRNA, uas yog ces txhais los ntawm tRNA molecules nqa cov amino acids los tsim ib tug polypeptide los yog protein ntau.

Ntawm no, dab tsi yog replication nyob rau hauv protein synthesis?

Rov ua dua yog cov txheej txheem uas lub xovtooj ntawm tes ua ib daim qauv ntawm nws tus kheej DNA (copy DNA -> DNA). Rov ua dua tshwm sim nyob rau hauv S-fase nyob rau hauv kev npaj rau cell division thaum lub sij hawm cov ntaub ntawv genetic ntaub ntawv rau lub synthesis ntawm cov proteins yog hloov los ntawm mothercell mus rau lub daughtercell.

Dab tsi yog protein synthesis siv rau?

Protein synthesis yog cov txheej txheem tag nrho cov hlwb siv rau ua cov proteins , uas yog lub luag haujlwm rau tag nrho cov qauv ntawm tes thiab kev ua haujlwm. Muaj ob txoj hauv kev tseem ceeb rau protein synthesis . Hauv kev sau ntawv, DNA tau theej rau mRNA, uas yog siv li ib tug template rau cov lus qhia ua protein ntau.
