Ribosomal subunits yog tsim los ntawm ribosomal RNA (rRNA) thiab proteins. Ribosomal subunits nrog S-nqi sib txawv yog tsim los ntawm cov molecules sib txawv ntawm rRNA, nrog rau cov protein sib txawv. Nco ntsoov tias RNA yog ib qho polymer ntawm ribonucleotides uas muaj nitrogenous puag adenine, uracil, guanine, los yog cytosine.
ribosomal subunits nyob qhov twg?
Eukaryote ribosomes yog tsim thiab sib 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).
Dab tsi yog qhov me me ribosomal subunit ua los ntawm?
Lub me me ribosomal subunit yog tsim los ntawm ib ribosomal RNA (rRNA) molecule. Hauv cov kab mob (Escherichia coli yuav raug siv los ua cov kab mob siv hauv kab lus no), nws yog hu ua 16S RNA raws li nws qhov nrawm nrawm. Hauv E. coli, 16S RNA muaj 1542 nucleotides.
Dab tsi ua rau ribosomal subunits nrog rRNA?
rRNA yog ib qho ribozyme uas ua cov protein synthesis hauv ribosomes. Ribosomal RNA yog transcribed los ntawm ribosomal DNA (rDNA) thiab ces khi rau ribosomal proteins los tsim me me thiab loj ribosome subunits. … Ribosomes muaj li ntawm 60% rRNA thiab 40% ribosomal proteins los ntawm pawg.
ribosome ua los ntawm dab tsi?
Ribosomes yog tsim los ntawmribosomal proteins thiab ribosomal RNA (rRNA). Hauv prokaryotes, ribosomes yog kwv yees li 40 feem pua ntawm cov protein thiab 60 feem pua rRNA.
