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.
