Every cell in your body is produced by cell division. Before each cell divides, it must copy its genetic material in a process called DNA replication. Understanding of DNA replication comes largely from studies of E. coli, bacteria that are found by the billions in your large intestine. Let's take a look at how DNA replication occurs in an E. coli cell. As we zoom in, we see the DNA. At the origin of replication, the two strands of DNA separate, serving as templates for making new strands. The result is a replication bubble. The bubble grows in both directions, forming two replication forks.
