DNA sequencing in genetic research
DNA sequencing in genetic research. Capillary electrophoresis (CE) equipment being used to sequence DNA (deoxyribonucleic acid). DNA sequencing determines the exact order of the four bases that make up a gene. Genes are regions of DNA that encode how every cell in the body works. Here, the DNA is cut into fragments and each base is labelled so that a detector can distinguish them. This method makes it possible to compare normal and abnormal versions of the same gene, which could reveal the exact cause of a genetic disease. Photographed at the AFM (French Muscular Dystrophy Association), Evry, France.
