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.
to allow the chromosomes to move without becoming entangled and breaking
Coiled and dense is their normal state, they uncoil breifly to reproduce, but dna reproduction is done before cell division
So cells can reproduce.
i dont know

The chromosomes condense during prophase, the first stage of both mitosis and meiosis.
mitosis
In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1. In mitosis, the homologous chromosomes dont interact, but in meosis, they separate during Anaphase 1.
During mitosis a double-stranded chromosome attaches to a spindle fiber centromere.
During the process of mitosis, the nucleus divides!
Chromosomes first become visible during prophase of mitosis when they condense and coil up tightly. This allows them to be easily seen under a microscope as separate structures.
what guides the chromosomes movement during mitosis
The chromosomes condense during prophase, the first stage of both mitosis and meiosis.
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.
Mitosis
The chromosomes coil up and condense during prophase
Chromosomes form during Prophase of Mitosis.
Both autosomes and sex chromosomes separate during mitosis./ Somatic chromosomes separate during mitosis with same number as in the parent cell.
All chromosomes are reproduced during mitosis.
