You grind up some potato, extracts the DNA from it and digests the DNA with two different restriction enzymes (separately, not together): EcoRI and BamHI. You then obtain the cloning vector, pUC19, and digest it with the same two enzymes. You then run a gel which is shown here. You notice that the cloning vector made nice, tight bands on the gel, but the potato DNA just looks like a smear with no distinct bands. However, this is just what you expected. Explain why there are so many bands. Which enzyme would be the better choice to use for cloning the potato DNA, EcoRI, or BamHI? Explain why?
