Essay Set 1: Essay 1. Identify differences and similarities between transcription in prokaryotes with that in eukaryotes. Address differences/similarities in transcriptional initiation, promoter elements, cellular location, possible regulatory mechanisms, and enzymes and key accessory proteins. Essay 2.  There are two major classes of membrane transport proteins:  pumps/transporters/carriers and channels. Compare and contrast these two groups of proteins (regulation, localization, activity, etc.). Provide a specific example of a transport protein for each of these two broad categories making sure to include their function and subcellular localization. Essay 3.  For proteins >60kD in size, transport across the nuclear envelope is a ‘receptor’ mediated process. Describe in detail this bidirectional transport process making sure to touch on proteins involved in both import and export processes and how the differential localization of Ran-GAP and Ran-GEF influences this process.
