How do prokaryotes and eukaryotes differ with respect to the number of open reading frames that are contained in a typical mRNA? Why does this difference make sense in view of the translation initiation strategies used by each type of organism? What consequences does this difference have for the regulation of coordinated gene expression in the two types of organisms—for example, how might a key regulator turn on a suite of related genes in prokaryotic or eukaryotic cells?

Last week we discussed the role of general transcription factors in forming the transcription initiation complex in eukaryotes. Next week we will look more closely at the regulation of gene expression and the role played by specific transcription factors. Prokaryotes and eukaryotes utilize very different mechanisms for determining which genes are turned on and off and when. In lieu of the prokaryotic operon model, eukaryotes employ a combinatorics approach utilizing both general and specific transcription factors. For this week’s forum,...
