WebJan 25, 2024 · Why do DNA fragments have a negative charge? Generally, a DNA fragment contains phosphate groups which have a negative charge. Hence DNA fragments are negatively charged thereby moving towards anode which is a positive rod,under the influence of an electric field during gel electrophoresis. WebYes the charge does affect the kinetics. In terms of DNA gel electrphoresis, DNA molecs already have a constant mass to charge ratio because every nucleotide has a -ve phosphate group. However for proteins (made up of different amino acids with varying charge) the charge can affect the kinetics. north county funeral homes
