Ribosomes yog me me protein factories pom nyob rau hauv hlwb. Lawv yog nyob rau hauv lub cytoplasm thiab nyob rau hauv lub ntxhib ER. Ribosomes zoo li me me dots ntawm ER thiab hauv cytoplasm. Ribosomes yog pom muaj nyob rau hauv cov nroj tsuag, tsiaj txhu, thiab kab mob hlwb.

Hais txog qhov no, ribosomes zoo li cas?

Ribosomes lawv tus kheej zoo li me me hamburger buns. Lawv yog ua los ntawm ob subunits: ib tug loj (lub sab saum toj bun) thiab ib tug me me (hauv qab bun). Ribosomes yog tsim nyob rau hauv lub nucleolus, ib pawg ntawm cov protein thiab RNA pom nyob rau hauv nruab nrab ntawm lub cell lub nucleus.

Ib yam li ntawd, ribosome txhais yooj yim yog dab tsi? Ribosomes yog cov cell organelle tseem ceeb. Nws ua RNA txhais lus, tsim cov proteins los ntawm cov amino acids siv tub txib RNA ua tus qauv. Ribosomes muaj nyob rau hauv tag nrho cov nyob hlwb, prokaryotes thiab eukaryotes. A ribosome yog ib qho sib xyaw ntawm cov protein thiab RNA uas pib tsim nyob rau hauv nucleolus ntawm ib lub cell.

Tib neeg kuj nug, ribosome ua dab tsi?

Muaj nuj nqi. Ribosomes yog cov kab me me uas muaj RNA thiab cuam tshuam cov proteins uas muaj nuj nqi rau synthesize cov proteins . Cov protein yog xav tau rau ntau lub zog ntawm tes xws li kho kev puas tsuaj los yog coj cov txheej txheem tshuaj. Ribosomes tuaj yeem pom nyob hauv lub nkoj cytoplasm los yog txuas rau endoplasmic reticulum

Cov ribosomes tsim li cas?

Eukaryote cov ribosomes yog ua thiab sib sau ua ke hauv lub 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).
