SSC MTS EXAM

Detailed explanation-1: -Eukaryotic chromosomes consist of repeated units of chromatin called nucleosomes, which were discovered by chemically digesting cellular nuclei and stripping away as much of the outer protein packaging from the DNA as possible.

Detailed explanation-2: -Three levels of structural organization of eukaryotic DNA in the cell nucleus are considered in this paper: (i) the chain of nucleosomes; (ii) the solenoidal or superbead (nucleomere) model of compactization of the nucleosomal fiber; (iii) the mode of suprasolenoidal DNP-packing–loops or domains.
