This Edvotek experiment introduces the use of restriction enzymes as a tool to digest DNA at specific nucleotide sequences. Bacteriophage lambda DNA has a linear structure and 6 Eco RI recognition sites. Separation by agarose gel electrophoresis of an Eco RI digest of lambda DNA will yield 6 bands (5 distinct bands, two are very close in size) corresponding to the DNA fragments.
• Introduce restriction enzymes and their ability to digest DNA at specific nucleotide sequences
• Understand how electrophoresis separates differently-sized molecules
• Perform agarose gel electrophoresis
• Load, run, analyze, compare and size lambda DNA cut with HindIII, lambda DNA cut with EcoRI, and uncut lambda DNA
