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.
