In the nucleus, DNA is often found wrapped up and linked to a variety of histone proteins in a structure called chromatin that is loosely confined. Chromatin coils tightly and condenses to produce chromosomes just before a cell divides.

Chromosomes do not form from DNA when cells are not dividing. Instead, it is discovered in a looser form known as chromatin. Contrary to chromosomes, chromatin is DNA in an uncondensed form and lacks a recognisable structure. The nucleus of eukaryotic cells houses chromatin.

Chromosomes in eukaryotic cells are made of chromatin, a compound of DNA and proteins. Nuclear DNA is extremely compressed and wrapped around nuclear proteins in order to fit inside the nucleus; it does not exist as free linear strands. There are two varieties of chromatin.
