you isolate a mature mrna from a mixed experimental sample. you want to determine if it is a eukaryotic or prokaryotic mrna. what can you look for in the mrna to distinguish between mature prokaryotic and eukaryotic mrnas?

Respuesta :

One should look for the presence and absence of a 3' tail and 5' cap to differentiate between prokaryotic and eukaryotic mRNAs.

The transcription products of prokaryotes and eukaryotes are prokaryotic and eukaryotic mRNA, respectively. All eukaryotic mRNAs have poly-A tails and caps in the 5' end. However, mRNAs produced by bacteria and other prokaryotes lack these two features.

some other differences between prokaryotic and eukaryotic mRNAs are:

  • The polycistronic nature of prokaryotic mRNA and the monocistronic nature of eukaryotic mRNA
  • Additionally, whereas eukaryotic mRNA only contains a single gene transcribed into an mRNA molecule, multiple structural genes of an operon are transcribed into a single mRNA.In addition,
  • transcription occurs concurrently with translation in prokaryotes, whereas transcription occurs after transcription in eukaryotes.
