(a) 1. DNA
2.H1 histone
3.core of histone molecules
(b) The non-bound nuclei found in prokaryotes do not have a well defined DNA structure organized around proteins, with the exception of the archaea where DNA is packaged to formnucleosomes. The nucleoid occupies a central position in the bacterial cell as the nucleus does in eukaryotic cells.
(c) Each individual nucleosome core particle consists of a complex ofeight histone proteins—two molecules each of histones H2A, H2B, H3, and H4—and double-stranded DNA that is 146 nucleotide pairs long. The histone octamer forms a protein core around which the double-stranded DNA is wound
