  • Dna Gel Electrophoresis Lab

    Dna Gel Electrophoresis Lab

    Introduction: Gel electrophoresis is a method used to separate DNA fragments based on size and charge. This technique uses a gel that acts like a filter with pores in which molecules travel through. There are two types of gel which can be used depending on the molecules being separated, polyacrylamide gel or agarose gel (Karcher, 1993). In this gel electrophoresis, 0.8% agarose gel is used (Rose, 2010). The gel is subjected to an electrical current
