The number of chromosomes in the nucleus before mitosis is dependent on the species. The exact number is called the ploidy of the animal.

How many chromosomes do you have in cells before and after mitosis?
You have 24 before, and 12 after.
What must haped in a nucleus before it can undergo mitosis?
The genome has to replicate before the cell can enter mitosis. Since the genome is contained within the nucleus, the genome first replicates and then the nuclear membrane slowly begins to degrade so the chromosomes can separate in an organized manner during anaphase of mitosis
What is mean by open mitosis and closed mitosis?
Open mitosis occurs in most animal cells where the nuclear envelope breaks down ("opens" before the chromosomes separate. Closed mitosis occurs in some fungi, such as Aspergillusand Saccharomycesspecies, where the chromosomes divide within an intact ("closed") cell nucleus.
What event must occur outside the nucleus before mitosis can begin?
Before mitosis can happen, the chromosomes inside the nucleus must separate to form identical pairs. This sets the stage for each of the daughter cells to have a copy of the DNA to replicate the full sequence.
In mitosis the nucleus does what before the cytoplasm?
in mitosis, the nucleus divides first, and then the cytoplasm.
What do chromosomes do before dividing in mitosis?
They double into more chromosomes.
When are chromosomes duplicated before or after mitosis?
during
How many chromosomes does the nucleus has after mitosis is complete?
The same amount as before it began. It split in two and had half the chromosomes then it join with another split cell and regained the number. (The actual amount can vary between species)
What do chromosomes do before mitosis?
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 or meiosis DNA coils into what?
Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
In a human nucleus just before cell division how many chromatids are present?
Normally in a cell, there are 92 chromatids, 2 per chromosome. However, when the chromosomes have duplicated before mitosis, there are twice as many, or 184.
Why are chromosomes called doubles chromosomes just before mitosis begins?
Amount of DNA that has been doubled
