Abstract:Deoxyribonucleic acid (DNA)
electrophoresis and blotting are techniques commonly used to visualise DNA. Both techniques use simple, inexpensive protocols that rely on fundamental properties of DNA, and these protocols have changed little since they were introduced. Electrophoresis relies on the negative electrical charge of DNA to draw these molecules through a gel, separating DNA molecules on the basis of size. Southern blotting makes use of sequence complementarity to identify specific DNA frag… Show more
