A restriction map of Xenopus laevis mitochondrial DNA.
The mitochondrial DNA from Xenopus laevis is a 17.4 x 10(3)-base-pair circular DNA molecule. The mapping of this DNA, using 19 different restriction endonucleases is reported here. The sites are as follows: 1 for BamHI, PstI, SacI, SalI, BalI; 2 for BglII, SacII, EcoRI, ClaI, 3 for XhoI, 4 for AvaI, XbaI, PvuII, 5 for HindIII, 6 for HhaI, BclI, HpaI, 10 for AvaII and 11 for HincII. The same sites (except for one of the two ClaI sites) are observed in the molecule cloned in pBR322 DNA. The fragments corresponding to 62 cleavage sites have all been ordered and precisely located. They provide suitable conditions for further investigations connected with the study of replication and nucleotide sequence determination of this molecule.
