This paper investigates which of the variouslegal notions proposed for human DNA is themost appropriate from an ontological viewpoint – unique legal status, private property, commonproperty, person, or information. The focus is onthe difficulties that private property, commonproperty and person present. By usingHarré''s notion of ``file-self'''' we arguethat, ontologically, the most appropriate legalnotion to be applied is information. This hasconsequences for storage, control and use ofgenetic information as well as identifiablehuman body material.
