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. WebPulsed-field gel electrophoresis (PFGE) is a laboratory technique used by scientists to produce a DNA fingerprint for a bacterial isolate. A bacterial isolate is a group of the same type of bacteria. ... If so, these database …
