How much DNA is in chromatin?

Stuart McLachlan  asked the Naked Scientists:
Hi Chris,

Are you able to tell me the relative amounts of DNA vs histones in chromatin?


What do you think?

What a bizzare question... I only know one answer to this, and it may not even be able to do that!

Histones, as far as I am aware are proteins that are part of multi-cellular organism. But they are unique in the sense that they arrange their DNA strutures to Nucleosomes - since they play a large role in gene regulation, but because of my lack of knowledge, I looked into a wiki source, and explained the rest:

''each human cell has about 1.8 meters of DNA, but wound on the histones it has about 90 millimeters (0.09 m) of chromatin, which, when duplicated and condensed during mitosis, result in about 120 micrometers of chromosomes''
