Kev sau ntawv yog tus txheej txheem uas cov ntaub ntawv nyob rau hauv ib tug strand ntawm DNA yog theej rau hauv ib tug tshiab molecule ntawm tub txib RNA (mRNA). DNA muaj kev nyab xeeb thiab ruaj khov khaws cov khoom siv caj ces hauv cov nuclei ntawm cov hlwb raws li kev siv, lossis qauv.
Ib yam li ntawd, cov kauj ruam hauv kev hloov pauv ntawm RNA yog dab tsi?
RNA transcription txheej txheem tshwm sim nyob rau hauv peb theem: pib , sawb elongation , thiab kev txiav txim . Thawj theem tshwm sim thaum lub RNA Polymerase -Promoter Complex khi rau cov noob txhawb nqa hauv DNA. Qhov no tseem tso cai rau kev tshawb nrhiav qhov pib ua ntu zus rau lub RNA polymerase.
Yuav ua li cas RNA polymerase paub qhov twg pib hloov cov noob rau hauv mRNA? RNA polymerase pib thaum lub enzyme txuas mus rau qee yam nucleotide ib ntus hu ua tus txhawb nqa thaum pib ntawm a noob . RNA polymerase khi rau a cov gene txhawb kom pib mRNA synthesis.
Ua raws li qhov no hauv kev txiav txim siab, kev txhais lus txhais tau zoo tshaj plaws li cas?
kev sau ntawv (tran-SKRIP-shun) Hauv biology, txheej txheem los ntawm lub xov tooj ntawm tes ua RNA luam ntawm ib daim DNA. Daim ntawv RNA no, hu ua messenger RNA (mRNA), nqa cov ntaub ntawv caj ces xav tau los ua cov proteins hauv ib lub cell.
Transcription thiab translation yog dab tsi?
DNA, RNA thiab protein synthesis Qhov no yog lub npe hu ua tib neeg genome. Cov txheej txheem uas DNA tau theej rau RNA hu ua kev sau ntawv , thiab qhov uas RNA siv los tsim cov proteins hu ua txhais lus.

Dab tsi yog Qhov Ib Feem Cuam Tshuam ntawm cov khoom hydrogen hauv cov methane ch4 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus los ntawm Element Element Symbol Mass Percent Hydrogen H 25.132% Carbon C 74.868%
Dab tsi yog 4 kauj ruam nyob rau hauv tus txheej txheem ntawm transcription?
Transcription muaj plaub kauj ruam: pib. Lub DNA molecule unwinds thiab sib cais los tsim ib tug me me qhib complex. Elongation. RNA polymerase txav raws tus qauv strand, ua ke ntawm mRNA molecule. Kev txiav txim. Hauv prokaryotes muaj ob txoj hauv kev uas tau txiav tawm. Kev ua haujlwm
Transcription hauv DNA Quizlet yog dab tsi?
Kev sau ntawv. lub synthesis ntawm mRNA nyob rau hauv kev coj ntawm DNA. RNA polymerase. ib qho enzyme siv los tsim pre-mRNA, khi rau ib ntus ntawm dNA hu ua tus txhawb nqa, cais DNA, sau ntawv tab sis tsuas yog siv ib txoj hlua hu ua coding strand ua tus qauv, 5' - 3'
Dab tsi yog pawg ntawm 3 nitrogen hauv paus hauv RNA hu ua?
Lub hauv paus mRNA tau muab faib ua peb pawg, hu ua codons. Txhua codon muaj cov txheej txheem ntxiv ntawm cov hauv paus, hu ua anticodon. Anticodons yog ib feem ntawm kev hloov RNA (tRNA) molecules
Yog vim li cas transcription yog ib kauj ruam tsim nyog nyob rau hauv protein synthesis?
Lub Art ntawm Protein Synthesis Nyob rau hauv eukaryotic hlwb, transcription tshwm sim nyob rau hauv lub nucleus. Thaum lub sijhawm sau ntawv, DNA yog siv los ua tus qauv los ua ib qho molecule of messenger RNA (mRNA). Thaum lub sij hawm kev txhais lus, cov noob caj noob ces hauv mRNA yog nyeem thiab siv los ua cov protein
