... 17. Move the insulin gene to the open ends of the plasmid. Fit the insulin gene into the ring so the complimentary bases line up. When you are sure the base pairing is correct, tape the ends to create one new, closed ring. The enzymes that connect the pieces of DNA are called ligases. Scissors are u ...

... complementary activity, restriction enzymes work as “scissors” capable of identifying and cleaving specific DNA sequences (Kelly and Smith 1970, Smith and Wilcox 1970), whereas ligases re-join two DNA strands and reconstitute the phosphodiester bonds (Weiss and Richardson 1967). Restriction enzymes ...

Chapter 4 Cellular Metabolism
... Enzymes are complex __proteins__that function to lower the activation energy of a reaction so it may begin and proceed more _rapidly_. Because they do this, enzymes are called _catalysts___. The substances the enzymes act on are called ___substrates. Each enzyme is specific. List 3 factors that may ...

Comparing DNA
... DNA samples can be compared by a method called gel electrophoresis. Gel electrophoresis is a technique used to separate DNA fragments based on size which produces a “fingerprint.” DNA, which has been cut with restriction enzymes, is placed in a gel (looks and feels like clear Jello). The gel is some ...
