Storing genetic material. Researcher removing a vial containing human tissue samples from a tray in a freezer. The DNA (deoxyribonucleic acid) in these tissues will be extracted and used to investigate the origins of inherited disorders. Cryogenic (sub-zero) storage of the cells preserves them indefinitely. Photographed at Leiden University Medical Centre, Leiden, The Netherlands.
