watch All cells need to divide and process is called cell division. There are several types of cell division.

mujeres solteras acarigua Bacterial cells divide by a process called binary fission. Although this is not directly needed for A level it is useful to know. Under optimum conditions bacteria can divide once every 20 minutes.

A bud starts to for at the cells surface and then the cell undergoes interphase to prepare the cell for division. The cell undergoes mitosis to allow nuclear division to occur. This will give the budding cell a nucleus that has an identical copy of the parents DNA. The the daughter cell will pinch off to produce a new genetically identical cell.
Eukaryotic cells can divide either by mitosis or meiosis. As both of these are huge topics in their own right I have set up separate pages on these topics.
