Chromatin
Detailed information:
A deoxyribonucleoprotein complex consisting of (1) double-stranded DNA molecules; (2) a basic protein called histone; and (3) other proteins. The latter protect the DNA from attack by enzymes. Chromatin occurs in the cell nucleus, where it forms chromosomes, the carriers of genes. Its name is derived from its sensitivity to biological stains.See Deoxyribonucleic Acid; Chromosome; Gene.
