Summary

Threeori elements (ori 2,ori 5, andori 7) have been sequenced inSaccharomyces cerevisiae strain Dip 2 and compared to the equivalentori elements of a second strain (B). Bothori 2 andori 5 exhibit 98% base matching between strains Dip 2 and B. In contrast, the thirdori element (ori 7) exhibits extensive sequence rearrangements whereby a segment located downstream in the consensus strain occurs within theori structure in Dip 2. This represents a novel polymorphic form of the yeast mitochondrial genome.
