Why do daughter cells need to be identical?
In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set. Before mitosis, the chromosomes are copied.
Are the two daughter cells genetically identical?
In terms of DNA content, or the amount of DNA, the daughter cells are identical to the parent. … In organisms, mitosis is a way to produce two daughter cells that will have different functions or become different cell types.
Why must daughter cells be identical to parent cells at the end of mitosis?
Before mitosis begins, the chromosomes in the nucleus of the cell undergo replication. This is because mitosis produces two daughter cells identical to the parent cell; so the number of chromosomes in the parent and daughter cells must be the same.
What happens if daughter cells are not identical?
If the chromosomes are divided unequally during mitosis, one daughter cell will have trisomy, meaning that it has three copies of one of the chromosomes instead of the usual two, and the other will be missing a chromosome. The general term for this imbalance of chromosome numbers is aneuploidy.
Are the daughter cells genetically identical to the parent cell in meiosis?
The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell.
How do the daughter cells compare to each other?
Throughout various phases of mitosis, these chromatid pairs are separated to opposite sides of the cell and this parent cell divides into two separate, but identical, daughter cells. … Homologous pairs are separated, and the two resulting daughter cells have half as many chromosomes per cell.
Why are the two cells produced by the cell cycle genetically identical?
Why are the two cells produced by the cell cycle genetically identical? The two cells are genetically identical because during S phase an exact copy of each DNA molecule was created. chromatids. Mitosis ensures that each new cell receives one of the two identical sister chromatids.
Why is it important that mitosis results in daughter cells that are exact copies of the original cell’s 46 chromosomes?
Why is it important that meiosis result in daughter cells that have half of the original cell’s chromosomes? It is important that mitosis results in the daughter cells due to growth and repair.
Why does mitosis create identical copies of daughter cells?
During telophase, the newly separated chromosomes reach the mitotic spindle and a nuclear membrane forms around each set of chromosomes, thus creating two separate nuclei inside the same cell. As Figure 4 illustrates, the cytoplasm then divides to produce two identical cells.
Why does the parent cell and both daughter cells must have the same number of chromosomes?
Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies – or ‘replicates’ – its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
