Polyacrylamide gel electrophoresis is then used to seperate and analyse the polynucleotide chains in sizes ranging between 15 and 1000 nucleotides on the basis of size. The four mixtures of radiolabelled polynucleotides are transferred into separate wells according to the nucleotide type. The nucleotides are run through the gel at a voltage of 1500 volts. Due to the fact that DNA strands are negatively charged they are attracted to the positive anode and therefore move down the gel towards the anode
