(Phys.org)—A trio of researchers affiliated with several institutions in Belgium has developed a bioinformatics tool that allows for comparing protein-coding genes of 36 inbred mouse strains to the C57BL/6J strain. In their paper published in Proceedings of the National Academy of Sciences, Steven Timmermans, Marc Van Montagu and Claude Libert describe the tool, the database they created using it and applications for other researchers.
