Automated DNA sequencing. View of a robot arm performing DNA (deoxyribonucleic acid) sequencing tasks. A technician (upper left) oversees the process. Robots are used to increase the speed and accuracy of the repetitive tasks involved in mapping and sequencing DNA. DNA is the molecule which contains all the instructions on how to build an organism. By studying the sequence of genes in the DNA (the "genetic code"), researchers hope to understand which parts of DNA have what specific purpose. Research such as this may aid the treatment of genetic diseases such as cystic fibrosis and muscular dystrophy.
