Transcription yuav siv sij hawm qhov chaw nyob rau hauv peb kauj ruam: pib , elongation, thiab txiav. Cov kauj ruam tau piav qhia hauv daim duab hauv qab no. Kev pib yog qhov pib ntawm transcription. Nws tshwm sim thaum lub enzyme RNA polymerase khi rau thaj tsam ntawm cov noob hu ua tus txhawb nqa.
Tsuas yog li ntawd, 6 kauj ruam ntawm kev sau ntawv yog dab tsi?
Cov Ntsiab Lus Tseem Ceeb: Cov kauj ruam ntawm Kev Hloov Hloov Hloov yog lub npe muab rau cov txheej txheem uas DNA tau theej los ua kom muaj kev sib txuas ntxiv ntawm RNA. RNA tom qab ntawd nkag mus rau kev txhais lus los ua cov protein. Cov kauj ruam tseem ceeb ntawm kev sau ntawv yog pib, txhawb kev tshem tawm, elongation, thiab kev txiav txim.
Tsis tas li ntawd, dab tsi yog cov txheej txheem ntawm transcription hauv biology? Kev sau ntawv yog cov txheej txheem nyob rau hauv uas ib tug gene's DNA sequence raug theej ( luam tawm ) los ua ib qho RNA molecule. RNA polymerase siv ib qho ntawm DNA strands (cov qauv strand) ua tus qauv los ua ib qho tshiab, ntxiv RNA molecule. Kev sau ntawv xaus hauv a txheej txheem hu ua termination.
Hauv qhov no, dab tsi yog cov kauj ruam ntawm kev sau ntawv quizlet?
Cov ntsiab lus hauv cov teeb no (3)
- Thawj kauj ruam. RNA polymerase unzips DNA ob helix (pib)
- Kauj ruam thib ob. RNA Nucleotides yog tsim los ntawm nucleotides hauv DNA template strand (Elongation)
- Kauj ruam peb. Lub mRNA uas yog tsim tawm ntawm lub nucleous (kev txiav tawm)
Yuav ua li cas thaum transcription?
Kev sau ntawv tshwm sim nyob rau hauv lub nucleus. Nws siv DNA ua tus qauv los ua RNA molecule. RNA ces tawm ntawm lub nucleus thiab mus rau ib tug ribosome nyob rau hauv lub cytoplasm, qhov twg txhais tshwm sim . Kev txhais lus nyeem cov noob caj noob ces hauv mRNA thiab ua rau cov protein.

Thawj kauj ruam hauv kev sau ntawv yog dab tsi?
Thawj kauj ruam ntawm kev sau ntawv yog hu ua pre-initiation. RNA polymerase thiab cofactors (generaltranscription yam) khi rau DNA thiab unwind nws, tsim ib tug pib npuas. Qhov chaw no muab RNA polymerase nkag mus rau asingle strand ntawm DNA molecule
Plaub kauj ruam ntawm kev sau ntawv yog dab tsi?
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
Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Koj ua li cas electron configuration kauj ruam yog kauj ruam?
Cov kauj ruam Nrhiav koj tus lej atomic. Txiav txim siab tus nqi ntawm lub atom. Nco cov npe ntawm cov orbitals. Nkag siab txog kev teeb tsa hluav taws xob. Nco qhov kev txiav txim ntawm lub orbitals. Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom. Siv lub sij hawm ntev raws li qhov pom kev luv luv
