||"The period between the termination of DNA replication and
septation, sometimes known as the D period in
, is also
relatively constant, at about 20 min (primary source). During this period,
the cell prepares for division by assembling a multicomponent
“divisome” comprising several proteins. The major component
of this assembly is a tubulin-like protein, FtsZ, which forms a
ring at the site of septation that is thought to contract to bring
about division (reviewed in reference 26). The extent to which
the division and DNA replication cycles are coupled or interconnected is not yet clear (34)."
