What is Mitosis?
|
It's the process that ensures the same amount and kind of genetic material is transmitted from one generation to the next as the cells reproduce.
|
|
Name all the mitosis stages
|
 Stages |
|
Where does Mitosis occur?
|
In every cell of an organism except sex cells
|
|
Why doesn't Mitosis occur in sex cells?
|
Because mitosis replicates a cell so that it can repair , for example, torn skin. If mitosis was to happen in sex cells, every person produced from the parent will look exactly the same as the parent.

|
What is the fibre called that separates the chromosomes?
|

|
|
Crossing over occurs during which stage?
|
Prophase 1
|
|
