Genetic fingerprinting

... into fragments which are separated into bands during agarose gel electrophoresis . Next, the bands of DNA are transferred via a technique called southern blotting from the agarose gel to a nylon membrane. This is treated with a radioactively-labelled DNA probe which binds to certain and specific DNA ...
