Characterization of the inverted duplication in the mitochondrial DNA of Candida albicans.

The mitochondrial DNA (mtDNA) of Candida albicans contains a large inverted duplication. As is the case with most chloroplast DNAs and one other mtDNA, the nonduplicated regions of the molecule occur in two orientations with respect to each other, indicating that internal recombination occurs. Like some other mtDNAs, the C. albicans mtDNA contains a single SalI restriction site located near one end of the large rRNA gene. In contrast to other cases, however, the inverted duplication does not appear to contain any sequences coding for rRNA
