Heterogeneous mitochondrial DNA D-loop sequences in bovine tissue.

abstract：:Nuclear DNA from eucaryotes contains a significant fraction which forms duplexes very rapidly and also independently of the DNA concentration. This fraction can be isolated by adsorption to hydroxylapatite and has been called foldback DNA (Britten and Smith, 1970). Here we extend previous studies to show that the fold...
