Why is it important for dna to condense into chromosomes

During mitosis, the condensation of chromosomes takes place which is important for cell in several ways. Each DNA is more than 2 meter long therefore to fit it in the small size of the nucleus and to prevent its tangling cell need to condense the DNA into small units.

Condensation of DNA forms an organized structure in the form of a chromosome that helps in easy separation of chromosome during the time of cell division.

The condensation is also required to form functional genes and to regulate the binding of proteins to these gene thereby regulating the gene activation. Therefore DNA needs to condense into chromosomes.
