0 the type of cell division in which one cell divides into two cells that are exactly the same, each with the same number of chromosomes as the original cell: --
Our skin cells are continually replaced by mitosis.
1 the type of cell division in which one cell divides into two cells exactly the same, each with the same number of chromosomes (= cell structures) as the original cell --
During mitosis the endoplasmic reticulum is known to aggregate within the asters of the mitotic apparatus.
This mechanism is most clearly manifested during the first mitosis.
We focused on the regulation of the first and the second mitosis.
The other two smaller cells top of the figure have not started mitosis yet.
When pronuclear heterokaryons enter the first mitosis, their nuclei condense and metaphase chromosomes are visualised.
In normal human cells, the mutant is not present as an endogenous enzyme; the wild-type enzyme is only expressed before mitosis.
It would be more accurate to say that the centre was undergoing a kind of spatial mitosis.
We cannot exclude the possibility that the spindle assembly checkpoint acts during the first mitosis.
