Caption: Genetic sequencing. Technician preparing samples for gel electrophoresis. This technique is used to separate nucleotide bases from DNA (deoxyribonucleic acid) fragments. The bases are separated in sequence, giving a map of the DNA sampled. The DNA fragments are placed in a porous gel that has an electric current applied to it. The nucleotides move down the gel according to their size. After the process has run the bases appear as bands on the gel. The sequences of bases make up genes, which encode an organism's genetic information.
