Prototype Automated DNA Gene Sequencer, United States, 1987
Determining the sequence of bases in a small length of DNA was achieved in the 1970s. This machine, developed in 1987, automates the time-consuming process. The sequence is read by a laser and appears on screen or on a print out. The machine uses the Sanger method, named after Frederick Sanger (b. 1918), a British biochemist who first determined a process for DNA sequencing. This work won him his second Nobel Prize, in 1980.

Glossary: DNA bases
DNA stores the information, or blueprints, of every cell and is located in the genes. It is made up of two strands which form a double helix that is linked by hydrogen bonds. It was first described in 1953 by Francis Crick and James Watson.
Glossary: Nobel Prize
Awarded annually for outstanding work in physics, chemistry, physiology or medicine, literature, economics, and the promotion of peace.
Glossary: DNA sequencer
