Figure 1From: Flip-flop around the origin and terminus of replication in prokaryotic genomesThe topology of bi-directional replication of a circular prokaryotic chromosome. The continuous line is the DNA strand replicated as the leading strand; the dashed line is the DNA strand replicated as the lagging strand; Ori, the origin of replication; Ter, the terminus of replication. Ori and Ter divide the chromosome into two replichores, arbitrarily called left and right.Back to article page
