||Primary source abstract: "Here, [investigators] report the results of an international collaboration to produce a high-quality draft sequence of the mouse genome. [They] also present an initial comparative analysis of the mouse and human genomes, describing some of the insights that can be gleaned from the two sequences."
||P.8584 left column 3rd paragraph: "Recent genome analysis has brought quantification to the impressions about conservation. More than 80 metazoan genomes have now been sequenced, and a typical case is the mouse (primary source). Of its total set of gene sequences, 23% are shared with prokaryotes, a further 29% are shared with non-animal eukaryotes (protists, fungi, and plants), and a further 27% are shared with nonchordate animals. Thus, 79% of mouse genes retain pre-Cambrian sequences. Reciprocally stated, only 21% of its functional components are unique to chordates, much less vertebrates, mammals, or mice."
