To be more organized, to save space. Because DNA is so long, the cell compacts them using histones to form nucleosomes, which are again compacted to form the chromosomes. This way, the cell can save more space while it is undergoing mitosis or meiosis.

DNA is folded into chromosomes to ensure that it can be packed tightly and efficiently within the cell nucleus. This compact packaging allows for the large amount of genetic material to fit into a small space. Additionally, the folding of DNA into chromosomes helps to regulate gene expression and ensure the accurate segregation of genetic material during cell division.
