Answer 2

c. To avoid the genetic material to be tangled away during cell division

The nucleus divides before the cell divides in eukaryotic cells. Mitosis is the process through which the nucleus splits. A cell's DNA is copied before it undergoes mitosis. This is required so that each daughter cell has a complete copy of the parent cell's genetic material.

Chromosomes are DNA and protein-coated helical structures. During cell division, chromosomes are the form of a cell's genetic material. The appropriate segregation of the chromosomes during cell division is ensured by this coiled arrangement. DNA is not coiled into chromosomes at other stages of the cell cycle. Instead, it exists as chromatin, a granular substance.
