How does mitosis ensure that each daughter nucleus receives a complete set of chromosomes?
During the S phase of mitosis (within interphase) DNA is synthesized and replicated making sister chromosomes. The cell then progresses and eventually gets to anaphase, in which the chromosomes get pulled apart by the centromeres holding the 2 sister chromosomes together. This way the daughter cells will have the same exact DNA as the parents cell, one with the same DNA, one with an exact copy.
What else can I help you with?
Which phase chromosomes are distributed equally to daughter cells?
During anaphase of mitosis, sister chromatids are separated and become individual chromosomes that are then distributed equally to the daughter cells. This ensures that each daughter cell receives a complete and identical set of chromosomes.
What plays an important part in mitosis?
The spindle apparatus plays an important part in mitosis. It is responsible for segregating the chromosomes into two daughter cells by attaching to and moving the sister chromatids. This process ensures that each daughter cell receives an equal and complete set of chromosomes.
In mitosis how many chromosomes are in each daughter cell?
It depends on the species--humans, for example, will have 46 chromosomes in each daughter cell after mitosis, while a dog will have 78. In mitosis, the number of chromosomes in each daughter cell is equal to the number of chromosomes in the interphase parent cell.
What is the genetic makeup of the final product of mitosis?
Mitosis produces two genetically identical daughter cells which are diploid (2n), meaning that they have two sets of homologous chromosomes (chromosomes with genes for the same characteristics).
How many chromosomes are left after mitosis?
After mitosis, the number of chromosomes remains the same as the original cell. This is because mitosis is a process of cell division where the replicated chromosomes are equally distributed to each daughter cell, ensuring each cell receives a complete set of chromosomes.
What is reduced by a process called mitosis?
Mitosis reduces the chromosome number by half, ensuring that each daughter cell receives a complete set of chromosomes identical to the parent cell. This process is crucial for growth, repair, and asexual reproduction in organisms.
Do sister chromatids become individual chromosomes during mitosis?
Yes, sister chromatids separate and become individual chromosomes during mitosis. This process ensures that each daughter cell receives a complete set of chromosomes.
What can you say about the number of chromosomes received by each daughter cells after mitosis?
The number of chromosomes that each daughter cell has after mitosis is equal to the number of chromosomes in the original (parent) cell.
Does mitosis result in two daughter cells?
Yes; most cell reproduction is mitosis; where the number of chromosomes is the same in the daughter cells and the parent cells.
When a body cell divides through the process of mitosis the chromosomes in the daughter cells?
The chromosomes in the daughter cells are identical to the parent cell, with the same number and type of chromosomes. Each daughter cell receives a complete set of chromosomes, ensuring genetic continuity. This process is essential for growth, repair, and maintenance of the body.
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 you compare the parent cell to the daughter in mitosis what can be said about their chromosomes?
the daughter cells' chromosomes are a identical to the parent cell. they each have a complete set
