The cellular material that is made up of only DNA and proteins is called as chromosome.
It is made up of the DNA which makes up the genetic material in a given organisms along with proteins that help in the packaging of the DNA into a more compact and stable structure.
So it is basically the DNA along with binding proteins.
Since the DNA is negatively charged the proteins that are associated with the DNA are positively charged basic proteins.
The proteins involved are the packaging proteins as well as the chaperone proteins.
