Before mitosis begins, the chromosomes in a cell replicate. This occurs during the S (synthesis) phase. Chromosomes need to replicate so that when the cell divides at the end of mitosis, the daughter cells each recieve a copy of the chromosomes.
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
Before mitosis begins, a cell has a diploid number of chromosomes, which means there are two sets of chromosomes. This is because during interphase, before mitosis begins, the DNA has already replicated, so the cell contains identical copies of each chromosome.
Body cells are the only cells that go through the process of mitosis. So body cells have 46 chromosomes or 23 chromosome pairs. Before the cells separate the chromosomes duplicate and split so that the new cell has an identical DexyriboNucleicAcid.
Before the nuclear envelope of a cell breaks down during the mitosis process, the DNA has to be duplicated. After the envelope dissolves, the chromosomes separate, then the cell finally splits.
The phase of mitosis when chromosomes attach to the spindle fibers is the metaphase. During metaphase, the chromosomes align along the equatorial plane of the cell before being separated and pulled to opposite poles during anaphase.
Before mitosis, cells have a diploid number of chromosomes, which means they have 46 chromosomes in humans. After mitosis, the daughter cells also have a diploid number of chromosomes, so they also have 46 chromosomes.
They double into more chromosomes.
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
If an Allium cell has 30 chromosomes before Mitosis, then each daughter cell will also have 30 chromosomes after Mitosis. This is because during Mitosis, the chromosomes replicate and are equally distributed between the two daughter cells.

The number of chromosomes in the nucleus before mitosis is dependent on the species. The exact number is called the ploidy of the animal.
Before mitosis begins, a cell has a diploid number of chromosomes, which means there are two sets of chromosomes. This is because during interphase, before mitosis begins, the DNA has already replicated, so the cell contains identical copies of each chromosome.
Chromosomes form during cell division, specifically during the process of mitosis. During mitosis, the chromosomes condense and line up before being separated into two daughter cells.
Amount of DNA that has been doubled

Interphase. The process of meiosis has many similarities to the process of mitosis: chromosomes replicate before the process begins, and shorten and thicken to look like the chromosomes at the beginning of mitosis (condensation).
They are in need of reproduction.
