A chromosome is very tightly packed DNA. DNA stores the information that is used to synthesize proteins. Thus the entire makeup and organization of an organism relies on the information stored in the chromosomes.
DNA becomes wrapped around proteins known as histones. 8 histones form a structure known as a nucleosome. Multiple nucleosomes condense together with the addition of another histone, H1 to form a 30 nanometer fiber. Scaffolding proteins further pack the 30 nanometer fiber into a chromosome.
