The bacterial chromosome is a single, short, complex mass attached to the mesosome or to the plasma membrane. It is Called a chromosome. DNA is the genetic material present in their chromosomes. Chromosomes carry a large number of positively charged ions to balance the PO4- group of DNA. The replication of chromosomes continues throughout the cycle.
