DNA analysis. Researcher examining electrophoresis gels showing DNA (deoxyribonucleic acid) sequences. Gel electrophoresis is a technique used to analyse the molecular composition of DNA samples. The extracted DNA is placed into a gel,which then has an electrical current passed through it that separates the DNA molecules based on their size and charge. This technique is also used to analyse the protein composition of cells and tissues | |
