Brianna Noriega In order to analyze a dna molecule in a molecular biology lab you must determine the length in nucleotide pairs. Electrophoresis is an extremely useful tool in order to compare the mobility on agarose gels with dna markers of known lengths. Dna is a polymer that is negatively charged due to the sugar phosphates. When dna is on an electric field such as the electrophoresis gel the different lengths of dna migrate at different rates when they move through the porous gel. The ends
