Nyob rau hauv ob qho tib si prokayotes thiab eukaryotes nquag ribosomes yog tsim los ntawm ob lub subunits hu ua qhov loj thiab me subunit. … Thaum tsis ua haujlwm, ribosomes faib ua ob lub subunits, loj thiab me. Raws li cov protein synthesis pib, ib qho me me thiab ib lub subunit loj tuaj ua ke los tsim cov ribosome nquag.
Dab tsi yog subunits ntawm ribosome?
Ribosomes yog tsim los ntawm ob lub subunits nrog ntom ntawm 50S thiab 30S("S" yog hais txog ib chav tsev ntawm qhov ntom hu ua Svedberg unit). Lub 30S subunit muaj 16S rRNA thiab 21 proteins; 50S subunit muaj 5S thiab 23S rRNA thiab 31 proteins. … Ribosomal subunits yog tsim los ntawm ribosomal RNA (rRNA) thiab cov proteins.
YPuas yog ribosomes muaj 2 subunits?
Ribosomes yog tsim los ntawm ob lub subunits, qhov loj thiab me subunit, ob qho tib si ntawm cov uas muaj ribosomal RNA (rRNA) molecules thiab tus naj npawb ntawm cov ribosomal proteins sib txawv. Ob peb yam proteins catalyze cov kauj ruam sib txawv ntawm cov protein synthesis los ntawm kev khi ib ntus mus rau ribosome.
50S thiab 30S subunits yog dab tsi?
The 70S ribosome yog tsim los ntawm 50S thiab 30S subunits. 50S subunit muaj 23S thiab 5S rRNA thaum lub 30S subunit muaj 16S rRNA. … Cov intermediates ntawm 30S subunit tawm los 21S thiab 30S hais thaum lub intermediates ntawm 50S subunit tawm los 32S, 43S, thiab 50S hais.
ribosomal subunits nyob qhov twg?
Eukaryote ribosomes yog tsim thiabsib sau ua ke hauv the nucleolus. Ribosomal proteins nkag mus rau hauv nucleolus thiab ua ke nrog plaub rRNA strands los tsim ob lub ribosomal subunits (ib qho me me thiab ib qho loj) uas yuav ua kom tiav ribosome (saib daim duab 1).
