WebSo how does gel electrophoresis work? It is based on the principle that nucleic acids, like DNA and RNA, are negatively charged. This means that if you put nucleic acids in an electric field, they will migrate away from the negative end of the field and toward the positive end. The nucleic acids are placed inside the gel for two main reasons. WebGel electrophoresis is a molecular biology method used to analyze and separate DNA fragments based on their size. When you use gel electrophoresis to help you with molecular cloning, you will also need to be able to interpret and analyze the results of your gel. For example, you may need to excise your digested plasmid DNA from agarose.
