Why are chromosomes called doubles chromosomes just before mitosis begins?
Amount of DNA that has been doubled
What does a chromosome make of itself in cell division?
Chromosomes are copied during S phase, before cell division begins. This is so that each daughter cell receives the right amount of genetic material. In mitosis, the daughter cells receive the same number of chromosomes as in the original cell, in meiosis they receive half of this.
Describe how the chromosomes pairs are numbered?
It all begins from mitosis. Mitosis is the process of the cell division. Mitosis starts when the chromatin within the cell begins to rearrange into orderly strand called chromosomes. The chromosomes then move into pairs. After that, the chromosome pairs begin to pull apart from each other. Eventually, the chromosome pairs split apart into two new cells with the same makeupas the original cell.
What happens before meiosis begin?
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).
What are the two daughter cells of mitosis?
All somatic (body) cells at one point or another are involved in mitosis. The only cells that do not undergo mitosis, are the sex cells, sperm and ovum cells. Every body cell from liver to nerve cells undergo mitosis at least once. Though some undergo mitosis more often than other, skin cells for example almost constantly undergoing mitosis, while some cells like nerve cells, undergo mitosis only once or twice.
Why is it important that mitosis result in daughter cells that are exact copies of the original cell's W chromosomes?
As part of the cell cycle, mitosis involves partitioning the replicated chromosomes between two new nuclear compartments. Mitosis is a type of cell division that creates genetically identical daughter cells in which the number of chromosomes is kept constant. Mitosis can be considered an equational division, which has another name for this reason. Mitosis is the process by which a cell divides into two daughter cells with nearly equal amounts of cytoplasm, organelles, and cell membrane. It typically begins with the S phase of interphase and is followed by telophase and cytokinesis. Mitosis is a series of events that occurs during the M phase of the cell cycle in animals, resulting in the creation of two daughter cells genetically identical to the mother cell.
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.

Meiossis is cell division in which the number of chromosomes?
Before mitosis begins, the cell replicates its chromosomes (so the chromosome number doubles). Then during/after mitosis the cell splits in half - so each daughter cell produced by mitosis has the same chromosome number as the original cell.
What does telophase do?
The daughter chromosomes begin to unwind into chromatin, the nucleolus reappears, & the nuclear evelope begins to re-form. The mitotic apparatus disassembles, thus terminating mitosis.
What form around the two chromosome groups at the end of mitosis?
Cytoplasm
Why are DNA strands wound into the tight gene packages of chromosomes before mitosis begins?

What happens in telophase?
the final stage of meiosis or mitosis, in which the separated chromosomes reach the opposite poles of the dividing cell and the nuclei of the daughter cells form around the two sets of chromosomes.

Why is DNA replication required prior to mitosis?
Because mitosis produces 2 genetically identical cells, each cell must have an equal amount of DNA as the parent cell had. Because of this, the DNA makes a duplicate copy of itself before mitosis begins, so that when the chromosomes separate each cell that forms will have as much DNA as the parent cell.
What happens before meiosis begin?
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).
