Muaj ob hom nucleic acids uas yog polymers pom nyob rau hauv tag nrho cov nyob hlwb. Deoxyribonucleic Acid (DNA) feem ntau pom muaj nyob rau hauv lub nucleus ntawm lub cell, thaum Ribonucleic Acid (RNA) pom tsuas yog nyob rau hauv lub cytoplasm ntawm celltab sis nws yog feem ntau synthesized nyob rau hauv lub nucleus.
RNA nyob qhov twg?
RNA feem ntau pom hauv the cytoplasm. Txawm li cas los xij, nws yog synthesized nyob rau hauv lub nucleus qhov twg DNA tau txais kev hloov pauv los tsim tus xa xov RNA.
RNA Feem ntau pom nyob qhov twg?
Daim ntawv ntau tshaj ntawm RNA yog rRNA lossis ribosomal RNA vim nws yog lub luag haujlwm rau coding thiab tsim tag nrho cov proteins hauv hlwb. rRNA muaj nyob rau hauv cytoplasm ntawm cov hlwbthiab cuam tshuam nrog ribosomes.
Qhov chaw ntawm RNA nyob hauv cell yog dab tsi?
Teb: RNA tshwm sim hauv cytoplasm ib feem ntawm cell. RNA yog ribonucleic acid uas pab tsim cov protein synthesis hauv peb lub cev. Hauv tib neeg lub cev, cov nucleic acid no yog lub luag haujlwm rau kev tsim cov hlwb tshiab.
YPuas RNA pom hauv ribosomes?
Ribosomal RNA (rRNA)
rRNAs muaj nyob hauv ribosomes thiab suav txog 80% ntawm tag nrho RNA tam sim no nyob rau hauv lub cell. Ribosomes yog tsim los ntawm ib tug loj subunit hu ua lub 50S thiab ib tug me me subunit hu ua lub 30S, txhua tus yog tsim los ntawm nws tus kheej tshwj xeeb rRNA molecules.
