In general it is thought that during DNA replication, each strand of the replicating bacterial DNA attaches to proteins at what will become the cell division plane. As the bacterium grows to full size, the newly replicated chromosomes become separated. In the center of the bacterium, a group of proteins called Fts proteins interact to form a ring at the cell division plane. These proteins form the cell division apparatus known as the divisome. Proteins at the divisome are thought to synthesize the peptidoglycan and new membrane material that both splits the bacterium into two daughter cells and subsequently enables each to grow to full size.
