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.

Yog li ntawd, qhov twg yog ribosomes synthesized?

Hauv cov kab mob kab mob, ribosomes yog synthesized 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 tsam hauv lub cell nucleus.

Ib tug kuj tseem nug, dab tsi yog ribosome thiab nws txoj haujlwm? Muaj nuj nqi ntawm Ribosomes . Ribosomes yog cov qauv cell uas ua rau cov protein. Protein xav tau rau ntau lub cell muaj nuj nqi xws li kho kev puas tsuaj los yog coj cov txheej txheem tshuaj. Ribosomes tuaj yeem pom ntab hauv cytoplasm lossis txuas rau endoplasmic reticulum. Proteins yog ib feem tseem ceeb ntawm txhua lub hlwb.

Xav txog qhov no, ribosome tsim li cas?

Eukaryote cov ribosomes yog tsim thiab sib sau ua ke hauv cov nucleolus. Ribosomal cov proteins nkag mus rau hauv nucleolus thiab ua ke nrog plaub rRNA strands los tsim ob ribosomal ua subunits (ib qho me me thiab ib qho loj) uas yuav ua kom tiav ribosome (saib daim duab 1).

Dab tsi yog ribosomes hauv biology?

-sōm'] Ib tug kheej kheej-zoo li tus qauv nyob rau hauv lub cytoplasm ntawm ib tug cell uas yog tsim ntawm RNA thiab protein thiab yog qhov chaw ntawm protein synthesis. Ribosomes yog dawb nyob rau hauv lub cytoplasm thiab feem ntau txuas mus rau daim nyias nyias ntawm endoplasmic reticulum. Ribosomes muaj nyob rau hauv ob qho tib si eukaryotic thiab prokaryotic hlwb.
