If you needed a short piece of string but all you had was a long one, what would you do? You would probably grab a pair of scissors and cut it to the length you needed. In a somewhat similar fashion, cells have mechanisms for cutting long strands of nucleic acid into shorter strands- a type of molecular scissors. There are several reasons why cells need to cut their DNA or RNA. In this lab students will explore what restriction enzymes do and determine electrophoresis fragment sizes by comparing bands to the molecular weight standards.
