Restriction endonuclease cleavage maps of rat and mouse mitochondrial DNAs

Mitochondrial DNA from an Old World mouse, Mus musculus, and from an Old World rat, Rattus norvegicus, contain 19 and 22 distinct sites, respectively, for the 8 restriction endonucleases, BamHI, EcoRI, HaeII, HhaI, HincII, HindIII, HpaI and PstI. The relative positions of the sites have been mapped by the study of partial and double enzyme digests. Some sites may been conserverd between the mouse and rat mitochondrial genomes.
