Nyob rau hauv cov kab mob feem ntau, cov qauv intracellular ntau tshaj plaws yog cov ribosome uas yog qhov chaw ntawm cov protein synthesis nyob rau hauv tag nrho cov kab mob nyob. Tag nrho cov prokaryotes muaj 70S (qhov twg S=Svedberg units) ribosomes thaum eukaryotes muaj 80S ribosomes loj hauv lawv cytosol. Lub 70S ribosome yog tsim los ntawm 50S thiab 30S subunits.
ribosomes pom nyob rau hauv cov kab mob nyob qhov twg?
Hauv cov kab mob, ribosomes yog synthesized hauv cytoplasm los ntawm kev hloov pauv ntawm ntau lub ribosome gene operons. Hauv eukaryotes, cov txheej txheem yuav siv ob qho tib si hauv cov cell cytoplasm thiab hauv cov nucleolus, uas yog ib cheeb tsam hauv lub cell nucleus.
Cov kab mob puas muaj 60S ribosomes?
Cov kab mob ribosomes yog tsim los ntawm ob lub subunits nrog ntom ntawm 50S thiab 30S, as opposed to 60S thiab 40S hauv eukaryotic cells.
Vim li cas ribosome muaj nyob rau hauv cov kab mob cell?
Ribosomes - Ribosomes yog microscopic "factories" pom nyob rau hauv tag nrho cov hlwb, nrog rau cov kab mob. Lawv txhais cov caj ces los ntawm cov lus molecular ntawm nucleic acid rau cov amino acids-lub tsev thaiv ntawm cov proteins.
S hauv 70S thiab 80S ribosome yog dab tsi?
Tsab ntawv 'S txhais tau tias Svedberg's Unit thiab nws sawv cev rau sedimentation coefficient; hauv ribosome.
