Considering the following situation: A cell has 2n of DNA, and divides. The two cells that formed each have n amount of DNA. They divide and the four cells that form now have 1/2n. If this continues, there would be almost no DNA left after the trillions of divisions required to produce a complex organism.
Another scenario: A cell divides and each cell receives n amount of DNA, and then duplicates the DNA and divides again. The resulting cells will only have only certain portions of the full genome.
So that each daughter cell gets a complete genetic complement.

What are the stages in animal mitosis?
The same as for any other type of mitosis. Mitosis is mitosis.... Mitosis is the duplication of a single cell without sexual recombination of DNA. In some species, mitosis can be a form of reproduction (asexual). In humans, mitosis is how you grow and repair wounds.
Are homologous chromosomes involved in the process of mitosis?
No, homologous chromosomes are not directly involved in the process of mitosis. Mitosis involves the division of a cell's replicated chromosomes into two identical daughter cells. Homologous chromosomes are pairs of chromosomes that carry similar genetic information but are not directly involved in mitosis.
Are homologous chromosomes present in both mitosis and meiosis?
Yes, homologous chromosomes are present in both mitosis and meiosis. In mitosis, homologous chromosomes do not pair up, while in meiosis, homologous chromosomes pair up during prophase I.
How are mitosis and meiosis alike?
Mitosis and meiosis are both processes involved in cell division. Both processes involve the duplication of genetic material and the separation of chromosomes. Additionally, both processes ensure the distribution of genetic material to daughter cells.
How are mitosis and mitosis similar?
they both involve duplicating chromosomes
If a cell begins mitosis with 36 chromosomes there will be chromosomes in each cell after mitosis and each daughter cell will be genetically?
If a cell begins mitosis with 36 chromosomes, each daughter cell after mitosis will also have 36 chromosomes. This is because mitosis results in the duplication and equal distribution of chromosomes to the two daughter cells. Additionally, each daughter cell will be genetically identical to the original cell and to each other, maintaining the same genetic material.
When does duplication of chromosomes occur?
when does the duplication of chromosomes occur?
Why is duplication of chromosome required before mitosis?
Because every cell in the human body contains the formula for our chromosomes. If the chromosomes don't reproduce, then new duplicate cells cannot be formed.
Do chromosomes double in mitosis?
No, chromosomes do not double in mitosis. Instead, the existing chromosomes are replicated during the S phase of the cell cycle, resulting in two identical sister chromatids for each chromosome. During mitosis, these sister chromatids are separated to form two new daughter cells with the same number of chromosomes as the parent cell.
What are the reproduction of chromosomes?
duplication
What condenses into an X shape before mitosis?
Chromosomes condense into an X shape before mitosis. During prophase, the chromatin in the nucleus begins to condense and coil, forming distinct X-shaped structures known as chromosomes. This condensation allows the chromosomes to be easily moved and segregated during cell division.
What is cell division and chromosome duplication?
MITOSIS
What are the stages in animal mitosis?

What is DNA called after duplication?
Chromosomes
Duplication of chromosomes occur in?
The replication of the chromosomes occurs during interphase.
What guide chromosomes during mitosis?
what guides the chromosomes movement during mitosis
A cell with 18 chromosomes enters mitosis At the end of mitosis there will be?
It will have 18 chromosomes at the end of mitosis.
