Electrophoresis is the movement of charged particles through a porous supporting media when subjected to an electric Field . • Cations move towards cathode. • Anions move towards anode . One of the basic tools of modern biotechnology is gene splicing.. This is the process of removing a functional DNA fragment ( a gene) from one organism and combining it with the DNA of another organism to study how the gene works.. lise schoonen. 14-12-’15. 1.
