The DNA from bacteriophage Lambda is a well-characterised linear molecule containing six recognition sites for Eco RI (5 distinct sites, 2 are very close in size). In this experiment, Lambda DNA is digested by the Eco RI endonuclease. The digestion products are analysed by agarose gel electrophoresis.
