1 The DNA + histone = chromatin definition: The DNA double helix in the cell nucleus is packaged by special proteins termed histones. 2  The formed protein/DNA complex is called chromatin.
The nucleus of each cell in our bodies contains approximately 1.8 metres of DNA in total, although each strand is less than one millionth of a centimetre thick. This DNA is tightly packed into structures called chromosomes, which consist of long chains of DNA and associated proteins.In eukaryotes, DNA molecules are tightly wound around proteins-called histone proteins-which provide structural support and play a role in controlling the activities of the genes.t belongs to a class of molecules called the nucleic acids, which are polynucleotides-that is, long chains of nucleotides. Each nucleotide consists of three components: 1  a nitrogenous base: cytosine (C), guanine (G), adenine (A) or thymine (T). 2  a five-carbon sugar molecule (deoxyribose in the case of DNA).
