WitrynaIn this process the bacterium, which is a single cell, divides into two identical daughter cells. Binary fission begins when the DNA of the bacterium divides into two (replicates). The bacterial cell then elongates and splits into two daughter cells each with identical DNA to the parent cell. Each daughter cell is a clone of the parent cell. WitrynaBacteria are prokaryotes with chromosomes made up of a single closed DNA circle and no well-defined nuclei or membrane-bound organelles. Bacterial cells are present in spheres, cylinders, spirals, and rods.
