Molecules ntawm rRNA yog synthesized nyob rau hauv thaj chaw tshwj xeeb ntawm lub cell nucleus hu ua nucleolus, uas tshwm sim raws li thaj chaw ntom ntom hauv lub nucleus thiab muaj cov noob uas encode rRNA.
TRNA thiab rRNA nyob qhov twg?
Nyob rau hauv eukaryotes, pre-rRNAs yog transcribed, tiav, thiab sib sau ua ke rau hauv ribosomes nyob rau hauv lub nucleolus, thaum pre-tRNAs yog transcribed thiab ua nyob rau hauv lub nucleus thiab ces tso rau hauv lub cytoplasm qhov twg lawv txuas rau dawb amino acids rau protein synthesis.
ribosomal proteins tsim nyob qhov twg?
Cov proteins thiab nucleic acids uas tsim cov ribosome sub-units yog tsim nyob rau hauv cov nucleolus thiab xa tawm los ntawm nuclear pores rau hauv cytoplasm. Ob lub sub-units tsis sib npaug ntawm qhov loj thiab muaj nyob hauv lub xeev no kom txog rau thaum yuav tsum tau siv. Lub sub-unit loj dua yog li ob zaug loj dua qhov me dua.
RNA synthesized nyob qhov twg?
Kev txhais lus yog txheej txheem ntawm kev sib txuas ribonucleic acid (RNA). Synthesis tshwm sim nyob rau hauv lub nucleus ntawm eukaryotic hlwb los yog nyob rau hauv lub cytoplasm ntawm prokaryotesthiab hloov cov noob caj noob ces los ntawm ib tug noob nyob rau hauv deoxyribonucleic acid (DNA) mus rau ib tug strand ntawm RNA uas ces directs protein synthesis.
Puas tib neeg muaj RNA?
Yog, tib neeg lub hlwb muaj RNA. Lawv yog cov tub txib caj ces nrog rau DNA. … Ribosomal RNA (rRNA) – tam sim no txuam nrog ribosomes. Nws muaj cov qauv tsim thiabcatalytic luag hauj lwm ua si nyob rau hauv protein synthesis.
