Eukaryote ribosomes yog tsim thiab sib sau ua ke hauv cov nucleolus. Ribosomal proteins nkag mus rau lub nucleolus thiab ua ke nrog plaub rRNA strands rautsim ob lub ribosomal subunits (ib qho me me thiab ib qho loj) uas yuav ua kom tiav ribosome (saib daim duab 1).
Yuav ua li cas ribosomal proteins ua?
Ribosomes muaj nyob rau hauv prokaryotic thiab eukaryotic hlwb; Hauv mitochondria, chloroplasts thiab kab mob. … Cov proteins thiab nucleic acids uas tsim cov ribosome sub-units yog tsim nyob rau hauv lub nucleolus thiab xa tawm los ntawm nuclear pores rau hauv cytoplasm.
Yuav ua li cas 2 yam ua ribosomal subunits?
Ribosomes yog tsim los ntawm ob lub subunits, qhov loj thiab me subunit, ob qho tib si muaj xws li ribosomal RNA (rRNA) molecules thiab tus lej sib txawv ntawm ribosomal proteins. Ob peb yam proteins catalyze cov kauj ruam sib txawv ntawm cov protein synthesis los ntawm kev khi ib ntus mus rau ribosome.
Vim li cas thiaj tsis muaj kev sib sau ntawm ribosomal subunits hauv ib lub cell?
Yog li ntawd, ribosomal proteins uas tuaj yeem hla txuas mus rau cov molecules hauv cov qauv ribosome yuav tsum tau khi rau lossis nyob ze ntawm RNA. Cov txheej txheem no yog thawj zaug uas tau tshwm sim ntawm cov proteins uas cuam tshuam nrog rRNA hauv eukaryotic ribosome qhov twg…
Cov qauv cell twg ua rau ribosomal subunits?
Txhua ribosome yog tsim los ntawm ib qho loj thiab me me. Ribosomal subunits yog tsimhauv cov nucleolus thiab tom qab ntawd xa tawm mus rau hauv cytoplasm, qhov chaw uas lawv khub tawm los ua tag nrho cov ribosomes. Feem ntau ob peb lub ribosomes txhais ib qho kev muab mRNA molecule ib txhij; Cov qauv no hu ua polysome.
