Mitosis is the division of?
nuclearIt is the division of the nucleus. Here the chromosomal number is not changed.
Why do cells need mitosis?
So they can surviveThey are important in increasing number of cells. It maintains chromosomal number
How is the chromosomal number of a cell kept constant throughout mitosis?
yes it is, in mitosis, a cell with a diploid number (2n) of chromosomes eg 46, will produce daughter cell of equal nd diploid number of chromosomes(46)
How the chromosomal number of the cell is kept constant through mitosis?
By uniform replication of DNA and division of centomeres, the daughter nuclei receive the same number of chromosomes.
How is the chromosome number halved during cell division: mitosis or meiosis?
The chromosome number is halved during cell division in meiosis, not mitosis.
How is the chromosomes number halved during cell division: through mitosis or meiosis?
The chromosomes number is halved during cell division through meiosis, not mitosis.
Why must gametes undergo meiosis instead of mitosis?
Gametes don't undergo Meiosis, but are CREATED in Meiosis.Gametes should be haploid. Otherwise chromosomal number will be doubled in offspring
Will chromosomal complement of daughter cells?
The chromosomal complement of daughter cells depends on the type of cell division occurring. In mitosis, daughter cells receive an identical set of chromosomes as the parent cell, maintaining the same chromosomal complement. In meiosis, the daughter cells have half the number of chromosomes, resulting in a haploid complement, which is essential for sexual reproduction.
Is the end product of mitosis haploid or diploid?
Mitosis produces DIPLOID cells- remember in mitosis your INCREASING the number of CELLS but the chromosome number is the SAME as the parentso a parent that has a (DIPLOID number of 10)will produce at the end of mitosis will produce 2 children with a diploid number of (10)That is why Mitosis is CONSERVATIVE.So in actuality, 1 diploid cell will produce 2 diploid cells in mitosisThe above is only true if the starting cell is itself diploid. However there are plenty of instances, especially in plants, in which cells that are haploid (the ones that give rise to pollen and egg, and endosperm nuclei, for example) or multiploid (hexaploid wheat, for example) undergo mitosis, and the cells that are produced have the same ploidy as the starting cell. Always. As noted above, mitosis is conservative. However, you ought not assume that you started with a diploid cell.
What process is responsible for abnormal karyotypes?
Abnormal karyotypes can result from processes such as chromosomal mutations, errors during meiosis or mitosis, exposure to mutagens, or genetic disorders. These processes can lead to changes in chromosome number (aneuploidy) or structure (translocations, deletions, duplications), resulting in abnormal karyotypes.
Why are root tip and embryo cells good for studying mitosis?
Root tip and embryo cells are good for studying mitosis because they are actively dividing cells, providing a large number of cells in various stages of mitosis for observation. This allows researchers to capture different phases of the cell cycle. Additionally, these cells have less cytoplasm and a simpler structure, making it easier to visualize the chromosomal movements during mitosis.
What happens to the chromosome number during mitosis?
During mitosis, the chromosome number remains the same. The cell duplicates its chromosomes before dividing, so each daughter cell receives the same number of chromosomes as the parent cell.
