Ib qho RNA molecule transcribed los ntawm DNA yog hu ua messenger RNA, los yog mRNA luv luv. Cov mRNA tam sim no txav deb ntawm DNA thiab tawm ntawm lub cell lub nucleus. Sab nraum lub nucleus, ribosomes txuas lawv tus kheej mus rau RNA.
Ib yam li ntawd, mRNA txuas rau dab tsi?
Thaum twg mRNA yog ua nyob rau hauv lub nucleus thaum transcription, nws tawm lub nucleus los ntawm lub nuclear pores mus rau hauv lub cytoplasm. Nws ces txuas rau lub ribosome qhov twg, qab zib-phosphate qaum qaum yog txuas rau qhov me me ntawm ribosome thiab ob codons yog nthuav tawm nyob rau hauv lub bigunit ntawm lub ribosome rau kev txhais lus.
Tsis tas li ntawd, mRNA mus qhov twg los ua cov protein? Neeg xa xov liaison RNA ( mRNA ), molecule hauv cov hlwb uas nqa cov lej los ntawm DNA hauv lub nucleus mus rau qhov chaw ntawm protein ntau synthesis nyob rau hauv lub cytoplasm (cov ribosomes).
Ib sab saum toj no, mRNA pom qhov twg thaum lub sijhawm txhais lus?
Hauv kev txhais lus , tub txib RNA ( mRNA ) yog decoded hauv lub ribosome decoding center los tsim ib tug tshwj xeeb amino acid saw, los yog polypeptide. Cov polypeptide tom qab folds rau hauv ib qho active protein thiab ua nws txoj haujlwm hauv lub cell.
mRNA nyob qhov twg?
Cov txheej txheem ntawm kev ua mRNA los ntawm DNA yog hu ua transcription, thiab nws tshwm sim nyob rau hauv lub nucleus. Cov mRNA directs lub synthesis ntawm cov protein, uas tshwm sim nyob rau hauv lub cytoplasm. mRNA ua Nyob rau hauv lub nucleus yog thauj tawm ntawm lub nucleus thiab mus rau hauv lub cytoplasm uas nws txuas mus rau lub ribosomes.

Qhov twg tshwm sim thawj lub teeb nyob ntawm qhov tshwm sim lossis lub teeb ywj pheej?
Lub Teeb-Dependent thiab Lub Teeb-Independent Reactions. Cov tshuaj tiv thaiv lub teeb, lossis cov tshuaj tiv thaiv lub teeb-dependent, yog thawj zaug. Peb hu lawv ob leeg thiab ob lub npe. Nyob rau hauv lub teeb-dependent tshwm sim ntawm photosynthesis, lub zog ntawm lub teeb propels lub electrons los ntawm ib tug photosystem mus rau lub high-zog lub xeev
Yuav ua li cas hloov DC tam sim no rau AC tam sim no?
Lub hwj chim inverter, los yog inverter, yog apowerelectronic ntaus ntawv los yog circuitry uas hloov directcurrent (DC) mus rau alternating tam sim no (AC).Inputvoltage, tso zis voltage thiab zaus, thiab overallpower tuav nyob ntawm tus tsim ntawm lub specificdeviceor circuitry
Dab tsi yog qhov txawv ntawm qhov tam sim no thiab cov khoom siv tam sim no?
Kev khiav ntawm electrons yog hu ua electron tam sim no. Electrons ntws los ntawm qhov tsis zoo terminal mus rau qhov zoo. Pa tam sim no los yog tam sim no yooj yim, coj zoo li cov neeg nqa khoom muaj txiaj ntsig ua rau tam sim no ntws. Pa tam sim no ntws los ntawm qhov zoo davhlau ya nyob twg mus rau qhov tsis zoo
Qhov twg yog qhov cua sov los ntawm qhov uas ua rau qhov tam sim no convection hauv lub mantle?
Lub tshav kub uas tsav cov convection tam sim no nyob rau hauv lub mantle los ntawm lub hauv paus ntawm lub ntiaj teb
Puas yog hluav taws xob tam sim no ntws los ntawm qhov tsis zoo mus rau qhov zoo?
Cov kws tshaj lij hluav taws xob hais tias, hauv hluav taws xob hluav taws xob, hluav taws xob ntws mus rau ib qho kev taw qhia: tawm ntawm qhov zoo ntawm lub roj teeb thiab rov qab mus rau qhov tsis zoo. Cov kws tshaj lij hauv hluav taws xob hais tias hluav taws xob ntws mus rau lwm qhov kev taw qhia: tawm ntawm qhov tsis zoo ntawm lub roj teeb thiab rov qab mus rau qhov zoo davhlau ya nyob twg
