Kev txiav tawm kev txiav tawm tshwm sim hauv cov tshuaj tiv thaiv ua ke rau RNA 3'-kawg ua haujlwmFeem ntau eukaryotic mRNA precursors raug cleaved hauv ib qhov chaw tshwj xeeb hauv cheeb tsam 3′-tsis tau txhais, ua raws. los ntawm polyadenylation ntawm cov khoom ntws cleavage. Cov protein ntau tau koom nrog hauv cov tshuaj tiv thaiv no.
Kev txhais lus nres li cas?
Kev txiav tawm
RNA polymerase yuav khaws cov ntawv sau kom txog thaum nws tau txais cov cim kom nres. Cov txheej txheem ntawm kev xaus lus yog hu ua kev txiav tawm, thiab nws tshwm sim thaum lub polymerase transcribes ib theem ntawm DNA hu ua terminator.
qhov txiaj ntsig ntawm kev txhais lus kawg nyob qhov twg?
Qhov tshwm sim ntawm Kev Tshaj Tawm yog a kev pub dawb ntawm messengerRNA (mRNA).
qhov kawg ntawm kev sau ntawv pib li cas?
Kev txhais ntawm ob lub noob. (a) RNA polymerase txav los ntawm 3′ kawg ntawm tus qauv strand, tsim RNA strand uas loj hlob hauv 5′ → 3′ kev taw qhia (vim tias nws yuav tsum yog antiparallel rau cov qauv strand).
Lub teeb liab nres yog dab tsi?
Rho-independent terminator Ib chav kawm ntawm cov teeb liab nres rau DNA transcription. Kev ncab ntawm DNA uas muaj cov kab ke uas tau rov ua dua nyob rau hauv qhov kev taw qhia rov qab thiab ua raws li txoj hlua luv ntawm adenines. Thaum theej rau hauv RNA, nws tsim ib lub voj plaub hau uas ua lub teeb liab kom tsis txhob muaj cov ntawv sau tseg.

Thaum twg thiab qhov twg siv cov ntawv sau npe thaum sau cov qauv tshuaj?
Ib qho tshuaj formula yog ib qho kev qhia uas qhia cov ntsiab lus hauv ib qho kev sib txuas thiab cov txheeb ze ntawm cov ntsiab lus. Yog tias tsuas yog ib qho atom ntawm ib hom tshwj xeeb yog tam sim no, tsis muaj subscript siv. Rau atoms uas muaj ob lossis ntau dua ntawm ib hom tshwj xeeb ntawm atom tam sim no, ib daim ntawv sau npe sau tom qab lub cim rau lub atom Dab tsi yog cov ntawv sau npe siv rau hauv cov qauv tshuaj?
Kev xa ntawv puas cuam tshuam rau kev sau ntawv michaela cullington?
Nyob rau hauv Cullington qhov kev tshawb pom, nws xaus lus tias texting muaj qhov cuam tshuam tsawg kawg rau kev sau ntawv Cullington pib nws qhov kev sib cav los ntawm kev qhia txog kev xa ntawv uas nws mam li cuam tshuam rau TextSpeak. Yog li ntawd, nws siv lub ntsiab lus ntawm TextSpeak ua tus choj los hais ob peb qhov kev txhawj xeeb tawm tsam nws qhov kev sib cav .
Qhov kev pab cuam adobe twg yog siv rau kev ntaus ntawv thiab sab hauv nplooj ntawv?
Rau kev ntaus ntawv thiab tsim cov ntaub ntawv, Adobe InDesign yog lub platform premiere. Cov software no tau tsim los pab cov neeg tsim cov ntsiab lus ntawm txhua yam los tsim cov ntaub ntawv ua haujlwm zoo thiab zoo nkauj. InDesign muab kev tswj xyuas kom tiav rau cov txheej txheem tsim cov ntaub ntawv .
Yuav hloov cov kua dej nres kom txhim kho kev nres tsheb?
Hloov cov dej nres yuav txhim kho braking muab tsis muaj teeb meem hauv qab ntawm koj lub braking systemCov dej nres yuav dhau los ua paug nrog dej thiab hlau los ntawm qhov chaw uas tsim cov braking system, hloov cov kua yuav tiv thaiv corrosion thiab cov khoom nws thiaj li tsis ua hauj lwm .
