DNA analysis. Automated pipette taking samples from vials for DNA (deoxyribonucleic acid) analysis. DNA is the molecule that controls the growth and development of all living things. It carries the genetic code in the form of genes, lengths of DNA that form recipes for body proteins. DNA information is stored as a sequence of four bases (adenine, thymine, guanine and cytosine) along the length of a DNA strand. Analysis of DNA sequences can lead to a greater understanding of how an organism functions.
