The DNA molecules are normally single-stranded.

DNA is negatively charged and histone proteins are positively charged; this helps them to associate closely and be packed tightly together in nucleosomes.

Nucleic acids have an intrinsic affinity for proteins and are bound closely to all of the proteins in the cell.
