Summary
Rat-liver mitochondrial DNA (mtDNA) contains 2 cleavage sites of the restriction endonuclease XbaI. The molecular sizes of restriction fragments are 6.6×106 and 3.7×106 D.
The results of partial cleavage of mtDNA with EcoRI allow the fragment F (0.32×106 D) to be localized in the sequence ABCEGFHDA. The functional map of mtDNA is constructed for two genes of the ATP-ase mRNAs from rat-liver mitochondria.
Molecular hybridization shows that the ATPase genes are located in fragment B and in the GEHD area of mtDNA EcoRI cleavage.
