Hauv cov kab mob kab mob, cov ribosomes yog ua ke nyob rau hauv lub cytoplasm los ntawm transcription ntawm ntau yam ribosome gene operons. Hauv eukaryotes, cov txheej txheem yuav siv ob qho tib si hauv cell cytoplasm thiab hauv nucleolus, uas yog thaj chaw hauv lub cell nucleus.

Kuj nug, dab tsi yog ribosome synthesis?

Synthesis . Cov synthesis ntawm cov ribosomes nws tus kheej yog txheej txheem nyuaj heev, yuav tsum muaj kev sib koom tes tso tawm los ntawm ntau ntau cov noob encoding ribosomal ua proteins thiab rRNAs. Thaum assembled, yuav luag tiav ribosomal ua Cov subunits raug xa tawm tawm ntawm lub nucleus thiab rov qab mus rau hauv cytoplasm rau cov kauj ruam kawg ntawm kev sib dhos.

Ib yam li ntawd, qhov twg mitochondrial ribosomes tsim? Muaj nuj nqi cov ribosomes yog macromolecular ribonucleoprotein nanomachines uas tau sib sau los ntawm rRNA (rRNA) thiab cov proteins. Ribosomes muaj nyob rau hauv cytoplasm ntawm cov kab mob thiab eukaryotic hlwb.

Ua raws li qhov no hauv kev xav, ua li cas ribosomes synthesize proteins?

Cov ribosome yog universally lub luag hauj lwm rau synthesizing cov protein los ntawm kev txhais cov genetic code transcribed nyob rau hauv mRNA mus rau hauv ib tug amino acid sequence. Ribosomes siv cellular accessory cov proteins , soluble hloov RNAs, thiab lub zog metabolic kom ua tiav qhov pib, elongation, thiab txiav tawm ntawm peptide synthesis.

Ob hom ribosomes yog dab tsi?

Muaj ob hom ribosomes , dawb thiab ruaj (tseem hu ua membrane bound). Lawv zoo ib yam nyob rau hauv cov qauv tab sis txawv nyob rau hauv qhov chaw nyob rau hauv lub cell. Dawb cov ribosomes nyob rau hauv lub cytosol thiab muaj peev xwm txav mus thoob plaws hauv lub cell, whereas tsau cov ribosomes yog txuas nrog rER.
