Draw a diagram of a typical agarose gel electrophoresis showing migration of undigested and digested sets of DNA fragments. Label (a) the digested and undigested DNA fragments, (b) Anode and cathode ends of the plate. Mention therole of electrophoresis in biotechnology.

This is a diagram of a typical agarose gel electrophoresis showing migration of undigested and digested sets of DNA fragments (along with the cathode and anode ends of the plate).

The role of electrophoresis is to separate and perform analysis of macromolecules (DNA, RNA and proteins) and their fragments, based on their size and charge.
