Full article >>>Chromatin is the structural building block of a
chromosome. It is found inside the
nucleus of a
cell and consists of a complex of
DNA and
protein in eukaryotic
cells. The
nucleic acids are generally in the form of double-
stranded
DNA (a
double helix).

chromosome consists of a single
molecule of
DNA complexed with an equal mass of
proteins. Collectively, the

chromatin.
