The chromosomes line up so that the sister chromatids can get separated by the pulling action of spindle fibres. These sister chromatids are then divided into the two cells - one cell gets each. The lining up is important so that there is equal division.
No, chromosomes do not undergo crossover during mitosis. Crossover, also known as genetic recombination, occurs during meiosis, not mitosis.
During prophase of mitosis, the chromatin coils and condenses to form tightly packed structures called chromosomes. This condensation allows for easier segregation of genetic material during cell division.
G2phase
In meiosis, chromosomes align in pairs during metaphase I, while in mitosis, chromosomes align individually during metaphase.
During metaphase of mitosis, the chromosomes become attached to the spindle fibers.
They first become visible during prophase of mitosis.
what guides the chromosomes movement during mitosis
Mitosis
The chromosomes coil up and condense during prophase
Chromosomes form during cell division, specifically during the process of mitosis. During mitosis, the chromosomes condense and line up before being separated into two daughter cells.
No, chromosomes do not undergo crossover during mitosis. Crossover, also known as genetic recombination, occurs during meiosis, not mitosis.
During prophase of mitosis, the chromatin coils and condenses to form tightly packed structures called chromosomes. This condensation allows for easier segregation of genetic material during cell division.
Condensation and shortening of chromosomes occur during the prophase stage of mitosis. In prophase, the chromatin fibers condense and coil tightly to form distinct, visible chromosomes.
G2phase
Both autosomes and sex chromosomes separate during mitosis./ Somatic chromosomes separate during mitosis with same number as in the parent cell.
Chromosomes attach to the mitotic spindle during the metaphase of mitosis. Part of the answer depends on how you define the stages of mitosis and not everybody does this the same way. The short answer is all of them.
It is possible to count chromosomes only during vell division (mitosis or meiosis). This is because when the cell is not dividing the chromosomes are in an uncoiled, extended state and are not visible under the microscope. During cell division the chromosomes coil up, becoming shorter and thicker and so visible. At this time they can be counted.
