Why are eukaryotic mRNAs not polycistronic, unlike some bacterial transcripts?
◦ Eukaryote's genetic code is non-overlapping, and so coding sequences cannot overlap on the same mRNA.
◦ Eukaryotes have more complex translational machinery than bacteria that is also less efficient in initiating translation.
◦ Eukaryotic mRNAs are generally shorter than bacteria mRNAs, and so do not contain sufficient information to encode additional polypeptides.
◦ Bacteria couple their translation with transcription, while eukaryotes do not.
◦ The eukaryotic ribosome must bind to the 5' end of the mRNA and scan, while the bacterial ribosome can bind to a Shine-Delgarno sequence anywhere in the mRNA.
