Some bacteria are capable of forming endospores through the process of sporulation. The endospore contains that bacterial genome and keeps the bacterium in a dormant state. It is formed when the vegetative cell forms a septum and divides asymmetrically. This action separates the DNA forespore from the cell to eventually form the endospore. The bacterial forms the endospore when in environment is not suitable for growth. It also allows the bacterium to be dormant when exposed to harsh chemicals, radiation or low nutrients.
