Introduction During the cell cycle, bacterial cells double their mass, replicate and segregate their chromosome, and synthesize the division septum, which is then split to generate two daughter cells. WebIn the first step, called interphase, the DNA strand of a chromosome is copied (the DNA strand is replicated) and this copied strand is attached to the original strand at a spot called the centromere. This new structure is called a bivalent chromosome.
