Ib yam cog cell synthesizes cov proteins Hauv peb qhov sib txawv: cytosol, plastids, thiab mitochondria. Kev txhais ntawm mRNAs transcribed nyob rau hauv lub nucleus tshwm sim hauv cytosol. Nyob rau hauv sib piv, ob transcription thiab translation ntawm plastid thiab mitochondrial mRNA coj qhov chaw nyob rau hauv cov organelles [2].

Ib yam li ntawd, koj tuaj yeem nug, qhov chaw ntawm cov protein synthesis hauv cov nroj tsuag yog dab tsi?

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

Ib yam li ntawd, cov nroj tsuag ua cov proteins li cas? Nitrates thiab Amino Acids Nitrates muab tso rau hauv cog los ntawm cov hauv paus hniav yog rub mus rau hauv lub cog , qhov twg lawv hloov dua siab tshiab rau hauv 20 ntau hom amino acids. Cov amino acids no hloov mus ua cov proteins hauv cov qauv tshwj xeeb hauv cov hlwb hu ua ribosomes. Cov qauv no nyob hauv plaub qhov chaw hauv cog.

Ib yam li ntawd, qhov twg protein synthesis tshwm sim?

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 tug strand ntawm ribonucleic acid (RNA) yog ua ke.

Dab tsi tiv thaiv kev tsim cov protein?

Protein synthesis tshwm sim nyob rau hauv lub cytoplasm ntawm ribonucleoprotein hais, ribosomes. Chloramphenicol inhibits tus synthesis ntawm protein ntau nyob rau hauv cov kab mob thiab xaiv inhibits protein synthesis nyob rau hauv mitochondria thiab chloroplasts ntawm eukaryotic hlwb uas tau kawm (Sager, 1972).
