Explanation:

DNA double helix is very long molecule, but it fits within a microscopic nucleus due to packaging. Histone proteins help in wrapping the DNA, first in the form of chromatin, which could be seen in interphase nucleus. Further coiling and dehydration of chromatin leads to appearance of chromosome.
