ORC was first found in S. cerevisiae (where it may be called scORC), but similar complexes have now been characterized in Schizosaccharomyces pombe (spORC), Drosophila (DmORC), and Xenopus (XlORC). All of the ORC complexes bind to DNA.

If a stem cell divides symmetrically, have the ability to produce either two stem cells (increasing the stem cell pool by one) or two committed cells (decreasing the pool by one). This is called symmetrical renewing or symmetrical differentiating.

Each set of ter sites allows a replication fork into the termination region, but does not allow it out the other side.For example, replication fork 1 can pass through terC and terB into the region, but it cannot continue past terE, -D, and -A. This arrangement creates a "replication fork trap."
