- In Eykaryotes is bidirectional too, but they need more than one beginning place (more than one origin of replication) in each chromosome. [Figure 3.jpg]

- Prokaryotes starts to replicate their DNA with only one origin (it can be sufficient). For example, in Escherichia coli, the beginning is the point Ori C which has 240 pb. [Figures 1.jpg and 2.jpg]
