Mitosis is performed when a cell is required to produce two identical offspring.
Cells usually have two copies of chromosomes within the nucleus.
Mitosis is the process of splitting one cells to produce two identical copies:
|In a cell the chromosomes are contained within the nucleus.|
|When the cell receives the signal to replicate, the DNA replicates so that each arm of the chromosome is the same|
|The chromosomes then line up and are pulled apart by cell fibres called mitotic spindles.|
|The nuclear membranes then begin to form again|
|When the nuclear membranes are formed fully the cell splits and forms to identical cells|
Mitosis is primarily used in a sexual reproduction, this type of
reproduction has no variation and is mainly used in plants
