Most bacterial species contain a single type of chromosome, but it may be present in multiple copies. Several thousand different genes are interspersed throughout the chromosome; structural gene sequences (encoding proteins) account for the majority of bacterial DNA; nontranscribed DNA sequences between adjacent genes are termed intergenic regions.
The cell structure is simpler than that of other organisms as there is no nucleus or membrane bound organelles. Instead their control centre containing the genetic information is contained in a single loop of DNA. Some bacteria have an extra circle of genetic material called a plasmid.ach daughter cell is a clone of the parent cell. When conditions are favourable such as the right temperature and nutrients are available, some bacteria like Escherichia coli can divide every 20 minutes. This means that in just 7 hours one bacterium can generate 2,097,152 bacteria.
