About This Item

Description

Restriction enzymes are enzymes that are capable to cleaving, or cutting, DNA molecules in very specific spots based on the DNA molecule's sequence of bases. Their discovery and isolation in the latter half of the 20th century provided scientists with an invaluable tool and rapidly expanded in the field of molecular biology. Agarose electrophoresis is a technique for separating the pieces of DNA that result from the use of restriction enzymes. In this activity students will perform agarose electrophoresis on three DNA samples that have already been treated with restriction enzymes. One sample has been cut with the enzyme HindIII, one has been cut with the enzyme EcoRI, and one has been cut with both enzymes. The resulting pattern of DNA bands on the agarose gel will show that each enzyme affects the DNA differently. Students will not only learn about the process of DNA electrophoresis but learn the techniques associated with the process, such as setting up an agarose gel, loading DNA samples in the agarose gel, and staining the gel in order to visualize the DNA bands. They will also learn how to determine the sizes of unknown DNA fragments after examining their results.
