Chromosomes are composed of two chromatids during the prophase and metaphase of mitosis. The chromosomes of formed in prophase and line up in metaphase.
Spindle fibers are formed during the metaphase stage of mitosis (cell division) when the chromosomes are tightly condensed and aligned at the center of the cell. Spindle fibers pull the chromosomes in opposite directions toward the opposite poles thus allowing the daughter cells to obtain a copy of the genome
Cells formed during mitosis contain the same number of chromosomes as the parent cell - typically 46 chromosomes in human cells. This ensures that each daughter cell receives an identical set of genetic information.
The centromere is formed during the G2 phase of the cell cycle, as the cell prepares for cell division. It is essential for the proper alignment and segregation of chromosomes during mitosis.
No, a spindle is a structure formed during cell division (mitosis) to help separate chromosomes. It is not an organ, but rather a network of microtubules that helps move and segregate chromosomes during cell division.
During meiosis there is pairing between homologous chromosomes for exchange of chromatin material by crossing over and these chromosomes get separated in first stage of meiotic division, thus half of the chromosomes separate at each pole; the second stage of meiosis is more or less similar to mitotic division. At the end of meiosis 4 daughter nuclei are formed whereas in mitosis only 2 daughter nuclei are formed without reduction in the number of chromosomes.
46 chromosomes or 23 pairs
The two cells formed during mitosis are identical to each other and to the original parent cell. Each cell receives a complete set of chromosomes, ensuring genetic consistency.
Mitosis is a kind of cell division, where a parent cell splits into two identical daughter cells. Two cells are created during mitosis, but the original cell no longer exists so the total number will go up by one (or, if you're looking at multiple cells, the total number will double). The new cells have the same number of chromosomes as the original cell before it divided.
