Electrophoretic techniques that distinguish DNA fragments by size are essential in forensics and in the mapping of restriction sites within genes. The Analysis of Precut Lambda DNA Kit demonstrates basic procedures and principles of DNA gel electrophoresis, including agarose gel casting, sample loading, size-based separation of DNA fragments, DNA staining, and graphic analysis. This activity provides in-depth explanations about how restriction enzymes cut DNA and how electrophoresis can be used to separate and visualize DNA fragments.
