Unformatted text preview: Recombinant DNA Snuppy and CC the first cloned dog and cat Lat Friday’s lecture on genome Evolution: Read chapter 21. We have covered a lot of it already. I will work the rest in as we go along. Why are the ends of DNA fragments cut by most restriction enzymes called "sticky" ends? A) They are especially difficult to break. * B) They w ill hydrogen bond to the ends of other fragments. C) They w ill stick to RNA polymerase better than most DNA. D) They tend to stick to the sides of the test tube. E) They b ind tightly to the restriction enzyme. Why are the ends of DNA fragments cut by most restriction enzymes called "sticky" ends?
