Weba) Gel electrophoresis uses an electric field to move charged molecules through a gel matrix. In the case of DNA or RNA, the negatively charged phosphate groups of the nucleotides give the molecule an overall negative charge, causing it to move towards the positive electrode. 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.
