Once the ancestor is specified, the meaning of the name is fixed: the ancestor and all organisms which are its descendants are included in the taxon named. Listing all these organisms (i.e. providing a full circumscription) requires the complete phylogenetic tree to be known.
Some researchers perceive viruses not as virions alone, which they believe are just spores of an organism, but as a virocell - an ontologically mature viral organism that has cellular structure. [25] Such virus is a result of infection of a cell and shows all major physiological properties of other organisms: metabolism , growth, and ...
The genetic information is held within genes, and the complete assemblage in an organism is called its genotype. [75] DNA replication is a semiconservative process whereby each strand serves as a template for a new strand of DNA. [72] Mutations are heritable changes in DNA. [72]
The BHL digital content is indexed with the names of organisms using taxonomic indexing software developed by the Global Names project. The EOL project was initially backed by a US$50 million funding commitment, led by the MacArthur Foundation and the Sloan Foundation, who provided US$20 million and US$5 million, respectively.
Human taxonomy is the classification of the human species within zoological taxonomy. The systematic genus, Homo, is designed to include both anatomically modern humans and extinct varieties of archaic humans.

A proteome is the entire set of proteins that is, or can be, expressed by a genome, cell, tissue, or organism at a certain time. It is the set of expressed proteins in a given type of cell or organism, at a given time, under defined conditions. Proteomics is the study of the proteome.
The first printout of the human reference genome presented as a series of books, displayed at the Wellcome Collection, London. A reference genome (also known as a reference assembly) is a digital nucleic acid sequence database, assembled by scientists as a representative example of the set of genes in one idealized individual organism of a species.
