Cov txheej txheem ntawm tig DNA rau RNA mus rau synthesized rau hauv cellular proteins yog npe DNA kev sau ntawv. Transcription yog thawj kauj ruam los tsim cov proteins hauv cov hlwb.

Khaws qhov no hauv kev xav, dab tsi yog qhov txheej txheem ntawm kev ua RNA los ntawm DNA hu ua thiab nws tshwm sim qhov twg?

Kev sau ntawv siv qhov chaw nyob rau hauv lub nucleus. Nws siv DNA raws li tus qauv ua ib RNA molecule. RNA tom qab ntawd tawm hauv lub nucleus thiab mus rau ib qho ribosome hauv cytoplasm, qhov chaw txhais lus tshwm sim . Kev txhais lus nyeem cov noob caj noob ces hauv mRNA thiab ua ib protein.

Ib tug kuj yuav nug, dab tsi yog qhov txheej txheem ntawm kev sib sau cov protein los ntawm RNA hu ua? Cov txheej txheem ntawm kev sib sau cov protein los ntawm RNA hu ua transjahon thiab nws tshwm sim hauv ribosome. 8. Thaum tus tub txib RNA (mRNA) tau ua RNA base_U_ ib txwm ua khub nrog.

Ua raws li qhov no saib, dab tsi yog txheej txheem ntawm kev ua RNA los ntawm DNA?

Kev sau ntawv. Transcription yog txheej txheem los ntawm qhov DNA yog theej (transcribed) rau mRNA , uas nqa cov ntaub ntawv xav tau rau kev tsim cov protein. Transcription yuav siv sij hawm qhov chaw nyob rau hauv ob sab cov kauj ruam . Tus tub txib ua ntej RNA yog ces "edited" los tsim qhov xav tau mRNA molecule ib txheej txheem hu ua RNA splicing.

Lub cell ua RNA li cas?

Cells ua RNA cov lus hauv cov txheej txheem zoo ib yam li kev rov ua dua ntawm DNA. Cov DNA strands raug rub sib nrug nyob rau hauv qhov chaw ntawm cov noob yuav tsum tau transcribed, thiab enzymes tsim tus tub txib RNA los ntawm qhov sib lawv liag ntawm DNA bases siv lub hauv paus pairing cov cai. 3. RNA molecules ua hauv a cell yog siv ntau yam.

Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?

Cov txheej txheem spontaneous yog ib qho uas tshwm sim yam tsis muaj kev cuam tshuam ntawm sab nraud. Ib txoj kev uas tsis yog tshwm sim yuav tsis tshwm sim yog tias tsis muaj kev cuam tshuam ntawm sab nraud

Tus txheej txheem ntawm resizing tus lej yog dab tsi thaum koj muab faib los ntawm ib feem?

Teb: Scaling yog tus txheej txheem ntawm resizing tus lej los ntawm ib feem uas ntau dua los yog tsawg dua 1

Cov txheej txheem dab tsi uas tus kws tshawb fawb siv los tsim ntau cov ntawv luam ntawm DNA xav tau sau rau hauv daim ntawv dawb paug 1?

Molecular Cloning. Cloning tso cai rau tsim ntau cov ntawv luam ntawm cov noob, qhia cov noob, thiab kawm txog cov noob tshwj xeeb. Yuav kom tau txais cov DNA tawg rau hauv cov kab mob hauv cov kab mob hauv daim ntawv uas yuav tau theej lossis nthuav tawm, cov khoom tawg yog thawj zaug tso rau hauv plasmid

Tus txheej txheem yuam kev ntawm qhov txawv yog dab tsi?

Tus txheej txheem yuam kev rau qhov sib txawv ntawm ob txhais tau tias yog loj dua qhov standarderror ntawm ob txhais tau tias. Nws ntsuas qhov tsis paub tseeb. Qhov tsis paub tseeb ntawm qhov sib txawv ntawm ob txhais tau tias ntau dua qhov tsis paub tseeb hauv ob qho tib si. Yog li SE ntawm qhov sib txawv yog ntau dua li SEM, tab sis tsawg dua lawv cov lej
