MIP quiz 3
If you want to clone Gene 1 into the puC19 plasmid so it is in the same orientation as the
promoter, which of the following enzymes could you use to do this? Note: your amp gene
must be complete.
Note: ScaI, and SmaI are blunt end digesters. KpnI is a sticky end digester. - correct
answer-Kpn and SmaI to cut the plasmid and KpnI and ScaI to cut gene 1
