Human genome research. Gloved hand holding a tray containing part of the human genome. The 384 wells each hold a different fragment of cloned DNA. It takes 60 of these trays (23,040 wells) to hold the entire human genome. DNA (deoxyribonucleic acid) controls every characteristic of an organism. It is made up of two chains linked by bases. Specific sequences of bases (genes) perform a specific task within the living organism. The human genome project aims to find the base sequence of all the genes in human DNA, allowing for improved drug design and a greater understanding of genetic diseases. Photographed at the Sanger Centre in Cambridge, England.
