WebBacterial DNA is 1000 times longer than the cell that contains it. The DNA must be supercoiled in order to fit into the cell. The length of the single DNA molecule needed to carry the 4000 or so genes of a bacterial cell is about 1.5 mm, and this structure is compacted into 0.2 μm 3!Thus, a stretched out bacterial chromosome is a thousand … WebCell division in bacteria is accomplished by replication of the single circular DNA chromosome into two identical daughter duplexes. The replication fork in E. coli moves at the rate of about 20-30 µm per minute. Replication of the entire genome is completed in about 40 minutes. This is followed by partitioning of cell cytoplasm into two ...
