Before the nucleus starts dividing the process of DNA copying takes place
During mitosis, the chromosome number remains the same. The cell duplicates its chromosomes before dividing, so each daughter cell receives the same number of chromosomes as the parent cell.
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
Mitosis for sure has metaphase. Scientists are guessing that meiosis has it too, but they combine it and make it "prometaphase," because prophase and metaphase happens so fast in meiosis.
If you mean when "does" the nucleus divide to form two identical nuclei, the answer is during mitosis. Mitosis is the process of cell reproduction. During this process the DNA is duplicated before the nucleus spilts into two identical nuclei each with their own identical copy of the parent cell, creating two new identical daughter cells.
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.
in mitosis, the nucleus divides first, and then the cytoplasm.
They double into more chromosomes.
The number of chromosomes in the nucleus before mitosis is dependent on the species. The exact number is called the ploidy of the animal.
Mitosis keeps dividing the nucleus' into nuclei. If the processes in mitosis would be separate, then each stage woudn't function properly. One process must start before another one finishes.
The DNA doubles. heehee, long question, short answer. hope I helped. :3

During Mitosis, it isn't the nucleus itself that divides it is the chromatin inside the nucleus that duplicates during Prophase. This is so the new cells being created each have the correct amount of DNA for normal cell use.Because the nucleus is like the center of the cell. It tells the cell what to do and basically controls it.-6th grade science teacher
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.
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
