DNA replication starts at specific points. In prokaryotes, chromosomes are circular in structure. E. coli for example, has a single circular chromosome. In these structures oriC is the origin of replication.
Semiconservative replication occurs bi-directionally from this origin resulting in two copies of the original DNA with both containing one parent and one daughter strand[1]. Bi-directional replication produces two replication forks which migrating in opposite directions from oriC[2][3].
