Twice the number in the cell. So if the cell normally has 46 chromosomes, such as in somatic human cells, the dividing cell would have 92 chromosomes just before division. With germ cells such as sperm and egg this would be half that. Sperm and egg cells in humans would contain 23 chromosomes and 46 just before division.
With N representing the number of chromosomes in an organism:
Mitosis (somatic cells) 2N -> 4N division -> 2N

How many chromosomes will the new skin cells have?
Skin cells divide via mitosis - therefore the new cells will have the same number of chromosomes as the original cell. Therefore in humans, the new skin cells will have 46 chromosomes.
When chromosomes replicate they produce?
when the chromosomes are replicated the cells were about to divide into 2 cells (mitosis)
Can a mature red blood cell divide?
No, it cannot divide since mature red blood cells have no nucleus. there are no chromosomes to replicate.
How many chromosomes can be found in a Leksak bird's cells?
how many chromosomes can be found in each of the leksak birds cells
Has how many chromosomes withn the egg cells?
All human gametes (sex cells), which means egg cells and sperm cells, have 23 chromosomes. When the sperm fertilises the egg, the 23 chromosomes from the egg cell and the 23 chromosomes from the sperm cell join to make cells with 46 chromosomes. In summary, all cells in the human body have 46 chromosomes, except sperm cells and egg cells, which have 23.
What happens to DNA and chromosomes when cells in most parts of the body divide?
The DNA and chromosomes divide with it
How many chromosomes will the new skin cells have?
Skin cells divide via mitosis - therefore the new cells will have the same number of chromosomes as the original cell. Therefore in humans, the new skin cells will have 46 chromosomes.
Why do cells need to copy their chromosomes before they divide into two daughter cells?
They copy their chromosomes so that when they do divide into two different cells each one will have its own set of chromosomes and it couldn't be copied and transferred after divison occured
What types of cells divide this way for mitosis?
Chromosomes
When chromosomes replicate they produce?
when the chromosomes are replicated the cells were about to divide into 2 cells (mitosis)
For what reasons might a cell use meiosis?
All human cells have 46 chromosomes, 23 pairs. In sexual reproduction, if an egg and a sperm each with 46 chromosomes joined then the zygote would have 92 chromosomes. To keep this from happening, cells undergo meiosis. In meiosis the cells replicate the chromosomes and divide then divide again so they end up with only 23 chromosomes. Cells with half the number of chromosomes are called gametes.
When your cell undergo mitosis how many chromosomes do the new daughter cells have?
46.In humans, the only cells that divide by mitosis are ones with two sets of chromosomes, called diploid cells. They have 46 chromosomes, and the daughter-cells have 46 as well, because mitosis preserves the chromosome number.
How do you plant cells divide DNA if they don't have chromosomes?
Plants are higher level eukaryotic organisms and therefore contain chromosomes.
How many Chromosomes are in mosquito cells?
Somatic mosquito cells have 6 chromosomes
The period when cells devide to create cells is called?
It is mitosis - when the chromosomes within the cell divide and split forming two cells.
How many chromosomes do you have in your gamete cells?
23 chromosomes
Wheat has 42 chromosomes. How many chromosomes are in their body cells?
The 'body' cells have 42 chromosomes. The sex cells would have 21 chromosomes. 3 X 7
