Thaum elongation, RNA polymerase " taug kev" raws ib txoj hlua ntawm DNA, hu ua template strand, nyob rau hauv 3' mus rau 5' kev taw qhia. … Lub synthesized RNA tsuas yog nyob rau hauv lub template strand rau ib tug luv luv lub sij hawm, ces tawm lub polymerase raws li ib tug dangling hlua, tso cai rau lub DNA kaw rov qab thiab tsim ib ob helix.
RNA synthesized li cas?
RNA yog synthesized los ntawm DNA los ntawm ib tug enzyme hu ua RNA polymerase thaum lub sij hawm ib tug txheej txheem hu ua transcriptionRNA sequences tshiab yog complementary rau lawv DNA template, es tsis yog zoo tib yam luam ntawm lub qauv. RNA ces muab txhais ua cov proteins los ntawm cov qauv hu ua ribosomes.
RNA synthesized li cas thaum transcription?
Thaum kev sau ntawv, cov ntaub ntawv encoded hauv DNA yog siv los ua RNA. RNA polymerase synthesizes RNA, siv cov antisense strand ntawm DNA ua qauv los ntawm kev ntxiv RNA nucleotides ntxiv rau 3′ kawg ntawm txoj hlua loj hlob.
3 kauj ruam hauv RNA synthesis yog dab tsi?
RNA synthesis, zoo li yuav luag tag nrho cov tshuaj lom neeg polymerization tshwm sim, tshwm sim hauv peb theem: pib, elongation, thiab txiav tawm.
txheej txheem ntawm RNA synthesis tshwm sim nyob qhov twg?
Kev txhais yuav siv qhov chaw hauv lub nucleus. Nws siv DNA ua tus qauv los ua ib qho RNA (mRNA) molecule. Thaum lub sij hawm transcription, ib tug strand ntawm mRNA yog ua uas yog complementary rau ib tug strand ntawm DNA. Daim duab 1 qhia tias qhov no tshwm sim li cas.
