Daim ntawv thov
RNA thiab DNA yog siv los ua tshuaj.Tib neeg siv RNA / DNA ua ke los txhim kho kev nco thiab lub hlwb ntse, kho lossis tiv thaiv kab mob Alzheimer, kho kev nyuaj siab, ua kom muaj zog, ua kom tawv nqaij, ua kom muaj kev sib deev, thiab tiv thaiv kev laus.
RNA (abbreviated li RNA, Ribonucleic Acid) yog ib tug cab kuj ntawm genetic ntaub ntawv nyob rau hauv lub hlwb thiab nyob rau hauv ib co kab mob thiab cov kab mob zoo li tus kab mob.RNA muaj ribonucleotides condensed los ntawm phosphodiester bonds los tsim ib tug ntev chain-zoo li molecules.Lub ribonucleic acid molecule muaj phosphate, ribose thiab bases.muaj plaub lub hauv paus tseem ceeb hauv RNA, uas yog A (adenine), G (guanine), C (cytosine) thiab U (uracil), qhov twg U (uracil) hloov T (thymine) hauv DNA.Lub luag haujlwm ntawm RNA hauv lub cev feem ntau yog los tswj cov synthesis ntawm cov protein.
Ib lub cell hauv tib neeg lub cev muaj txog 10 pg ntawm RNA (muaj txog 7 pg ntawm DNA).Piv nrog DNA, RNA muaj ntau yam, me me molecular hnyav thiab loj variation nyob rau hauv cov ntsiab lus.RNA yuav muab faib ua tub txib RNA thiab tsis-coding RNA raws li cov qauv thiab muaj nuj nqi.Non-coding RNA muab faib mus rau hauv tsis-coding loj RNA thiab non-coding me RNA.Non-coding loj RNA suav nrog ribosomal RNA, ntev saw tsis-coding RNA.Non-coding me RNA suav nrog hloov RNA, nuclease, me me molecule RNA, thiab lwm yam.Me me molecule RNA (20 ~ 300nt) muaj xws li miRNA, SiRNA, piRNA, scRNA, snRNA, snoRNA, thiab lwm yam. Cov kab mob kuj muaj me me RNA molecule (50 ~ 500nt).
RNA, zoo li DNA, kuj yog cov saw hlau polynucleotide tsim los ntawm ntau yam nucleotides txuas los ntawm 3′,5′-phosphodiester bonds, tab sis txawv ntawm DNA hauv ntau txoj hauv kev.
