Txawm li cas los xij, polycistronic mRNAs paub tias muaj nyob hauv cov kab mob eukaryotic [5], yog li cov tshuab txhais lus eukaryotic yuav tsum muaj txoj hauv kev los daws lawv.
YPuas yog polycistronic mRNA hauv eukaryotes lossis prokaryotes?
Daim Ntawv Sau Tag Nrho
Polycistronic mRNA yog mRNA uas cov lej rau ntau yam khoom lag luam protein sib txawv. Feem ntau, Polycistronic mRNA pom muaj hauv prokaryotes.
YPuas yog eukaryotic mRNA Polycistronic lossis Monocistronic?
Eukaryotic mRNA molecule yog monocistronic vim muaj cov coding sequence nkaus xwb rau ib leeg polypeptide. Cov neeg prokaryotic zoo li cov kab mob thiab archaea muaj polycistronic mRNA. Cov mRNA no muaj cov ntawv sau tseg ntawm ntau lub noob ntawm cov txheej txheem metabolic.
Puas muaj Polycistronic noob hauv eukaryotes?
Ntau zaus ntawm polycistronic transcription hauv eukaryotes, los ntawm protists mus rau chordates, tau raug tshaj tawm. Cov no tuaj yeem yog faib ua ob hom dav. Dicistronic transcription units qhia tus neeg xa xov RNA (mRNA) encoding ob lub noob cais uas thauj mus rau cytoplasm thiab txhais hauv daim ntawv ntawd.
Vim li cas eukaryotic mRNA tsis Polycistronic?
Eukaryotic mRNAs yog feem ntau luv dua li cov kab mob mRNAs, thiab yog li tsis muaj cov ntaub ntawv txaus los encode ntxiv polypeptides. O Eukaryotes muaj cov tshuab txhais lus nyuaj dua li cov kab mob uas tsawg duamuaj txiaj ntsig hauv kev pib txhais lus.

Puas muaj leej twg muaj txoj sia nyob tsis muaj tus kab mob vwm?
Kev Kho Mob Tsis Paub: Tsuas yog Ib Tus Neeg Muaj sia nyob tus kab mob vwm yam tsis muaj tshuaj tiv thaiv - Tab sis ua li cas? Plaub xyoos tom qab nws yuav luag tuag los ntawm tus kab mob vwm, Jeanna Giese tau raug tshaj tawm raws li thawj tus neeg paub tias tau muaj tus kab mob no tsis tau txais tshuaj tiv thaiv.
Puas yog actinomycetes prokaryotes lossis eukaryotes?
Ob qho tib si kuj txawv ntawm cov fungi yog eukaryotes thaum Actinomycetes yog prokaryotes. Raws li prokaryotes, Actinomycetes tsis muaj nuclear-bound organelles (xws li nucleus, Golgi apparatus, thiab lwm yam) uas muaj nyob rau hauv cov kab mob fungal.
Puas muaj tsev neeg muaj koob muaj npe?
Ironed shoelaces Tub huabtais Charles muaj peb tus kheej valet, txhua tus mob siab rau tuav lub wardrobe ntawm tus huab tais thiab xaiv qhov nws yuav hnav. … Lawv yuav tsum tau khi txoj hlua khi ntawm txhua nkawm khau uas tus huab tais muaj.
Puas yog tsev neeg muaj koob muaj npe muaj lub cev tiv thaiv?
Tsis tas li ntawd, Tus Saib Xyuas tau tshaj tawm tias Royal Protection Squad, cov tub ceev xwm tseem ceeb tau them nyiaj tiv thaiv tus poj huab tais, kuj tseem ua haujlwm tiv thaiv "cov qub txeeg qub teg tam sim ntawd," uas yuav suav nrog Prince Charles, Prince William thiab Prince George.
Nyob hauv eukaryotes pyruvate hloov mus rau acetyl coa?
Nyob hauv cov hlwb eukaryotic, cov pyruvate molecules uas tsim thaum kawg ntawm glycolysis raug thauj mus rau mitochondria, uas yog qhov chaw ntawm cellular respiration. Nyob ntawd, pyruvate yuav hloov mus rau hauv ib pawg acetyl uas yuav tau khaws thiab qhib los ntawm cov cab kuj hu ua coenzyme A (CoA).
