- Use the following information to answer the next question In the process of genetic engineering, recombinant DNA is produced by combining genetic material from two different sources. For this technique, genetic engineers are especially interested in a specific group of enzymes called restriction endonuclease. These enzymes are preferred because they join the DNA fragments at 3' ends join the DNA fragments at 5' ends cut DNA at specific sites within the DNA cut DNA from their 5' or 3' endsarrow_forwardWhich of the following is NOT true of cutting DNA in biotechnology? O A. A molecular biologist can cut DNA using restriction enzymes. O B. DNA can be cut at specific base sequences called recognition sequences. OC. When DNA is cut in such a way that some of the bases are no longer paired with their complements, the unpaired ends of that DNA fragment are called sticky ends.
