Protein synthesis yog cov txheej txheem uas cov hlwb ua cov proteins . Nws tshwm sim nyob rau hauv ob theem: transcription thiab translation. Kev sau ntawv yog Kev hloov pauv ntawm cov lus qhia caj ces hauv DNA rau mRNA hauv lub nucleus. Tom qab mRNA yog ua tiav, nws nqa cov lus qhia rau ribosome hauv cytoplasm.

Tom qab ntawd, ua li cas koj ua cov protein synthesis?

Protein synthesis yog ua tiav los ntawm tus txheej txheem hu ua kev txhais lus. Tom qab DNA tau sau rau hauv tus tub txib RNA (mRNA) molecule thaum lub sijhawm sau ntawv, mRNA yuav tsum tau muab txhais los ua ib qho protein ntau . Hauv kev txhais lus, mRNA nrog rau kev hloov RNA (tRNA) thiab ribosomes ua haujlwm ua ke los tsim cov proteins.

Ib sab saum toj no, dab tsi yog 5 kauj ruam ntawm kev tsim cov protein? 5 Cov theem tseem ceeb ntawm Protein Synthesis (piav qhia nrog daim duab) |

  • (a) Ua kom cov amino acids:
  • (b) Hloov cov amino acid rau tRNA:
  • (c) Pib ntawm polypeptide saw:
  • (d) Chain Termination:
  • (e) Protein translocation:

Ib yam li ntawd ib tug yuav nug, qhov twg yog qhov chaw ntawm cov protein synthesis?

Protein yog sib sau ua ke hauv cov hlwb los ntawm ib qho organelle hu ua ribosome. Ribosomes muaj nyob rau hauv txhua hom cell loj thiab yog cov site ntawm protein synthesis.

Lub hom phiaj ntawm protein synthesis yog dab tsi?

Protein synthesis yog cov txheej txheem tag nrho cov hlwb siv los ua cov proteins , uas yog lub luag haujlwm rau tag nrho cov qauv ntawm tes thiab kev ua haujlwm. Hauv kev sau ntawv, DNA tau theej rau mRNA, uas yog siv los ua tus qauv rau cov lus qhia ua protein ntau . Hauv kauj ruam thib ob, kev txhais lus, mRNA yog nyeem los ntawm ribosome.
