Ribosomes yog tsim los ntawm ribosomal proteins thiab ribosomal RNA (rRNA). Hauv prokaryotes, ribosomes yog kwv yees li 40 feem pua cov protein thiab 60 feem pua rRNA. Hauv eukaryotes, ribosomes yog ib nrab ntawm cov protein thiab ib nrab rRNA.
ribosomes muaj dab tsi?
ribosome yog ib qho nyuaj molecule ua los ntawm ribosomal RNA molecules thiab proteins uas tsim lub Hoobkas rau cov protein synthesis hauv hlwb. Xyoo 1955, George E. Palade tau tshawb pom ribosomes thiab piav qhia tias lawv yog cov khoom me me hauv cytoplasm uas nyiam cuam tshuam nrog endoplasmic reticulum membrane.
Dab tsi yog qhov tseem ceeb hauv ribosome?
A ribosome yog tsim los ntawm RNA thiab cov proteins, thiab txhua ribosome muaj ob cais RNA-protein complexes, hu ua subunits me thiab loj.
ribosomes nyob qhov twg?
Ribosomes tsim nyob qhov twg? Lawv yog tsim nyob rau hauv the nucleolus. Lub luag haujlwm ntawm Ribosomes yog dab tsi? Lawv ua haujlwm hauv kev sib txuas ntawm cov protein.
YPuas yog cov proteins ua los ntawm ribosomes?
Ribosomes yog qhov chaw nyob hauv lub cell uas protein synthesis tshwm sim. … Nyob rau hauv lub ribosome, cov rRNA molecules coj cov catalytic kauj ruam ntawm protein synthesis - lub stitching ua ke ntawm cov amino acids los ua ib tug protein molecule. Qhov tseeb, rRNA qee zaum hu ua ribozyme lossis catalytic RNA los cuam tshuam qhov haujlwm no.
