In this article we will discuss about agarose gel electrophoresis. To know about quality and quantity of genomic DNA, agarose gel electrophoresis is performed on genomic and amplified DNA. Larger molecules migrate more slowly because of greater friction drag and they form their way through the pores of gel, less efficiently than smaller molecules. Range of separation in gel containing [...]
