A plasmid is 4000 bp in total.  It has an EcoRI cut site at position 1000, an XbaI cut site at position 2000, and a KpnI cut site at position 3000.  If the relaxed-form circular plasmid is cut with ALL three enzymes to completion (all sites are cut), how many bands would you see on an agarose electrophoretic gel on which you separated the fragments?

SA2a. (3 pts) Scenario 2: Carcinus maenas (The Green Crab) is native to Europe where it typically consumes European periwinkles snail species.  In recent decades the green crab has invaded the North American Pacific coast during the last few decades where it now successfully feeds on North American periwinkle snails that differ markedly from their European cousins in terms of size, shape, and shell strength. Name three things that you would need to show in order to demonstrate that natural selection is happening in periwinkle populations?
