The discovery of restriction enzymes nearly forty years ago revolutionized the study of DNA and accelerated our ability to both sequence and synthesize genomes. These enzymes opened the path to a ...

A second restriction enzyme digestion was carried out in situ in the gel, followed by electrophoresis in a second dimension perpendicular to the first electrophoresis. The 2-D pattern provides for the ...

What are enzymes? Enzymes are proteins that serve as catalysts to speed up biochemical reactions by breaking down larger molecules into smaller ones, says Dave Farina, a science educator and ...
