Because the daughter cells have to have the same number of chromosomes you began with.
When the cells go through mitosis the get split. If you split a cell with 46 chromosomes into two, you would only have 23 each.
That's why it needs to replicate beforehand. It will make sure the cells always have 46 chromosomes.

∙ 14y agobecause in mitosis the cells divide and in chromosomes cells function

∙ 12y agoChromosomes must be duplicated in order for the same amount of DNA to be transferred into the new cells formed by mitosis. If they do not duplicate, the new cells are mutated.

∙ 6y agoIn case of mitosis, you have two cells with the same chromosomes of the parent cell. For this purpose you must have double chromosomes. So chromosomes get divided.

How many rounds of chromosome replication occur in the cell?
how many rounds of chromosome replication occur i the cell pirior to mitosis
Why do chromosomes in parent cell duplicate during mitosis?
Chromosomes doubles during the S phase of inter-phase, which occurs before Mitosis. During the process of mitoses cell divides into 2 daughter cells from a single parent hence, before mitoses cells must duplicate so that each new cell has a sufficient set of genetic material.
Which phase occurs before mitosis or meiosis?
Inter-phase occurs before mitosis or meiosis.
What occurs when a segment breaks of chromosome breaks off and reattaches to another chromosome?
translocation
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.
Why is it important for the chomosome to make copies of themselves BEFORE mitosis occurs?
Because it has to duplicate itself before it goes through the process of mitosis.

Does mitosis ensure that each new eukaryote cell receives a copy of each chromosome?
Yes, it does! This occurs during G2 phase of Mitosis.
During what part of the mitosis process does the DAN replicate?
DNA replication occurs during the S phase of interphase, which is the phase that precedes mitosis. In this phase, the DNA molecules in the cell's nucleus are duplicated, resulting in two identical copies of each chromosome.
Does DNA occur before or after mitosis?
It occurs before mitosis, in the S-phase (synthesis) of interphase.
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.
If the chromosome number of a typical onion root tip cell is sixteen before mitosis what is the chromosome number of the each newly formed nucleus after nuclear division has taken place?
the same as before, each will have sixteen. If it was meyoses it would be 1/2 that (8) Mitotic division creates exact replicates of the original, so the answer is 16. Meosis occurs in the flower of the onion, it's sex cells ovules and pollen will have only 8 chromosomes
In what type of cell does mitosis occur?
Mitosis occurs in somatic cells. Meiosis, on the other hand, occurs only in sex cells or in the ovaries and testes.
What is the DNA of mitosis?
There is no DNA of mitosis. Before mitosis, the DNA must be replicated, which occurs during interphase of the cell cycle.
