Human genome research. Vessels containing yeast cultures incorporating human DNA fragments for the human genome project. The human DNA is present in yeast artificial chromosomes (YACs) in the yeast cells. It is cloned as the yeast reproduces, allowing analysis of the DNA. DNA (deoxyribonucleic acid) is the substance which controls every characteristic of an organism. The human genome project aims to find the base sequence of all human genes, allowing for improved drug design and a greater understanding of genetic diseases. Photographed at the Sanger Centre in Cambridge, England.
