Kev sau ntawv yog thaum RNA tsim los ntawm DNA. Cov ntaub ntawv yog theej los ntawm ib lub molecule mus rau lwm qhov. Cov DNA sib lawv liag yog theej los ntawm ib qho tshwj xeeb enzyme hu ua RNA polymerase los ua ib qho sib luag RNA strand. Kev sau ntawv yog thawj kauj ruam uas coj mus rau kev nthuav qhia ntawm cov noob.
Ib yam li ntawd, nws yog nug, dab tsi yog qhov txheej txheem ntawm kev sau ntawv?
Kev sau ntawv yog cov txheej txheem los ntawm qhov uas cov ntaub ntawv nyob rau hauv ib tug strand ntawm DNA yog theej rau hauv ib tug tshiab molecule ntawm messenger 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 tug kuj yuav nug, 3 kauj ruam tseem ceeb ntawm kev sau ntawv yog dab tsi? Transcription tshwm sim nyob rau hauv peb kauj ruam-pib, elongation, thiab termination-tag nrho cov qhia ntawm no.
- Kauj Ruam 1: Pib. Initiation yog qhov pib ntawm transcription.
- Kauj Ruam 2: Elongation. Elongation yog qhov sib ntxiv ntawm nucleotides rau mRNA strand.
- Kauj Ruam 3: Kev txiav txim.
Raws li txoj cai, 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.
Dab tsi yog 5 kauj ruam ntawm kev sau ntawv?
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.

Nws yog ib qho endothermic (siv cua sov) cov txheej txheem tshuaj uas siv lub hnub ci tig carbon dioxide rau hauv cov suab thaj uas lub xov tooj ntawm tes siv tau los ua lub zog. Raws li cov nroj tsuag, ntau hom algae, protists thiab kab mob siv nws kom tau zaub mov

Nws txhais tau hais tias tus naj npawb tiag tiag ntawm cov khoom uas tus neeg laus tuaj yeem tuav tau hauv STM yog los ntawm 5 txog 9, rau cov neeg feem coob thiab feem ntau cov dej num, txhua yam ua tsis tau tom qab txog 7 yam khoom tsis cuam tshuam, ces cov khoom yuav poob los yog tso tawm
Dab tsi yog qhov zoo thiab muab lus piav qhia luv luv ntawm nws?
Qhov zoo yog ib yam ntawm koj uas ua rau koj 'koj'. Thaum koj niam hais tias koj tau txais tag nrho koj qhov zoo tshaj plaws ntawm nws, nws txhais tau tias koj muaj lub ntsej muag luag ntxhi thiab lub siab zoo li nws muaj. Hauv kev tshawb fawb, kev zoo yog hais txog tus yam ntxwv uas tshwm sim los ntawm noob caj noob ces
