Recombinant DNA Technology Problem Set

Problem 10 Recombinant DNA 5

One of the most significant discoveries which allowed the development of recombinant DNA technology was:

A. the discovery of antibiotics used for selecting transformed bacteria.
B. the identification and isolation of restriction endonucleases permitting specific DNA cutting.
Prior to the discovery of these enzymes, there was no reproducible way to fragment DNA.
C. the discovery of DNA and RNA polymerase allowing workers to synthesize any DNA sequence.
D. the development of the polymerase chain reaction.
E. the Southern technique for separation and identification of DNA sequences.
