Three ori elements (ori 2, ori 5, and ori 7) have been sequenced in Saccharomyces cerevisiae strain Dip 2 and compared to the equivalent ori elements of a second strain (B). Both ori 2 and ori 5 exhibit 98% base matching between strains Dip 2 and B. In contrast, the third ori element (ori 7) exhibits extensive sequence rearrangements whereby a segment located downstream in the consensus strain occurs within the ori structure in Dip 2. This represents a novel polymorphic form of the yeast mitochondrial genome.
已对酿酒酵母菌株Dip 2中的三个ori元件（ori 2、ori 5和ori 7）进行了测序，并与第二个菌株（B）的等效ori元件进行了比较。菌株Dip 2和B之间的ori 2和ori 5均表现出98%的碱基匹配。相比之下，第三个ori元件（ori 7）表现出广泛的序列重排，即共有菌株中位于下游的一个片段出现在Dip 2的ori结构内。这代表了酵母线粒体基因组的一种新型多态形式。
