Los ntawm Wikipedia, dawb encyclopedia. RNA Nws yog lub npe hu ua ribonucleic acid, nucleic acid. Ntau yam sib txawv tam sim no paub. RNA Lub cev sib txawv ntawm DNA: DNA muaj ob txoj kab sib txuas, tab sis RNA tsuas muaj ib leeg xwb. RNA kuj muaj ntau lub hauv paus los ntawm DNA.

Ib yam li ntawd, RNA piav qhia yooj yim yog dab tsi?

Luv luv rau ribonucleic acid. Cov nucleic acid uas siv rau hauv cov txheej txheem metabolic tseem ceeb rau txhua kauj ruam ntawm kev tsim cov protein nyob hauv txhua lub hlwb thiab nqa cov ntaub ntawv caj ces ntawm ntau tus kab mob. Tsis zoo li ob-stranded DNA, RNA muaj ib txoj hlua ntawm nucleotides, thiab nws tshwm sim hauv ntau qhov ntev thiab cov duab.

Ib yam li ntawd, qee qhov piv txwv ntawm RNA yog dab tsi? Cov ntaub ntawv ntawm RNA suav nrog tus xa xov RNA (mRNA), hloov RNA (tRNA), thiab ribosomal RNA (rRNA).

Yog li ntawd, RNA yog dab tsi thiab nws ua haujlwm li cas?

Cov kab mob cellular siv cov tub txib RNA (mRNA) txhawm rau xa cov ntaub ntawv caj ces (siv cov hauv paus nitrogenous ntawm guanine, uracil, adenine, thiab cytosine, qhia los ntawm cov tsiaj ntawv G, U, A, thiab C) uas tswj cov synthesis ntawm cov proteins tshwj xeeb. Ntau tus kab mob encode lawv cov ntaub ntawv caj ces siv ib qho RNA genome.

Vim li cas RNA tseem ceeb heev?

RNA -hauv lub luag haujlwm no - yog "DNA luam theej duab" ntawm tes. Nyob rau hauv ib tug xov tooj ntawm kev kho mob tseem ceeb kab mob RNA , dua li DNA, nqa cov ntaub ntawv kab mob caj ces. RNA kuj ua si ib qho tseem ceeb Lub luag haujlwm hauv kev tswj cov txheej txheem ntawm tes - los ntawm kev faib cell, sib txawv thiab kev loj hlob mus rau cell aging thiab tuag.
