Kev faib tawm ntawm tus naj npawb ntawm nucleoli hauv ntau lub hlwb diploid pom ib hom ntawm ob lossis peb nucleoli rau nucleus, thiab qhov ntau ntawm 1 mus rau 6 nucle.
Tom qab ntawd, ib tug kuj yuav nug, puas muaj ib tug nucleus muaj ntau tshaj ib tug nucleolus?
Cov nucleolus yog ib qho non-membrane bound nuclear compartment pom nyob rau hauv eukaryotic hlwb uas yog qhov chaw ntawm ribosome biogenesis. Nroj tsuag thiab tsiaj nuclei tuaj yeem muaj ntau dua ib lub nucleolus.
Qhov thib ob, lub nucleolus muaj dab tsi? Cov nucleolus muaj DNA, RNA thiab proteins. Nws yog lub Hoobkas ribosome. Cells los ntawm lwm hom feem ntau muaj ntau nucleoli.
Ua qhov no saib, puas yog cov nucleolus hauv lub nucleus?
Cov nucleolus yog lub cev puag ncig nyob rau hauv lub nucleus ntawm eukaryotic cell. Nws tsis yog ib puag ncig los ntawm daim nyias nyias tab sis zaum nyob rau hauv lub nucleus . Cov nucleolus ua ribosomal subunits los ntawm cov proteins thiab ribosomal RNA, tseem hu ua rRNA.
Muaj pes tsawg nucleolus nyob hauv ib lub cell?
Ib lub nucleus tuaj yeem muaj txog li plaub nucleoli , tab sis nyob rau hauv txhua hom tus naj npawb ntawm nucleoli yog tsau. Tom qab lub cell faib, ib tug nucleolus yog tsim thaum chromosomes raug coj los ua ke rau hauv nucleolar cov cheeb tsam.
