Introduction

In prokaryotes such as E. coli and B. subtilis, chromosomal DNA exists in a circular fashion whereby DNA replication takes place at a common origin (oriC) [1]. Two replication forks move bidirectionally from oriC to replicate DNA until they meet, and the forks fuse with one another to form two circular daughter chromosomes [2]. The region where the two replication forks meet is defined as the “terminus region”, located roughly opposite of oriC[3].
