Nucleolus yog cov qauv loj tshaj plaws nyob rau hauv lub nucleus ntawm eukaryotic hlwb. Nws yog qhov zoo tshaj plaws hu ua qhov chaw ntawm ribosome biogenesis. Nucleoli tseem koom nrog hauv kev tsim cov teeb liab pom cov khoom thiab ua lub luag haujlwm hauv lub cell teb rau kev ntxhov siab.
Nucleolus tau txais nws lub npe li cas?
Cov qauv no tau txais kev txaus siab ntau nyob rau hauv cov hnub thaum ntxov ntawm lub teeb microscopy vim nws qhov tseem ceeb hauv lub cell. Nws yog thawj zaug piav nyob rau hauv thaum ntxov 1830s raws li ib tug "nucleus nyob rau hauv lub nucleus," nrog lub npe "nucleolus" coined los ntawm German physiologist Gabriel Gustav Valentin (Harris, 2009; Valentin, 1836).
Puas nucleolus txhais tias me ntsis nucleus?
of nucleus.] Etymology: [L., a me txiv ntoo, dim. ntawm nucleus.
Nucleolus yooj yim txhais yog dab tsi?
(noo-KLEE-uh-lus) Ib cheeb tsam hauv lub nucleus ntawm lub cell uas yog tsim los ntawm RNA thiab cov proteins thiab yog qhov chaw ribosomes tsim. Ribosomes pab txuas cov amino acids ua ke los tsim cov proteins. Lub nucleolus yog ib lub cell organelle.
Nucleolus ua dab tsi?
Nucleolus yog ib qho dynamic membrane-tsawg qauv uas nws lub luag haujlwm tseem ceeb yog ribosomal RNA (rRNA) synthesis thiab ribosome biogenesis.
