19. 3 DNA iS coiled in arrays of nucleosomes Core DNa is the 146 bp of dna contained on a core particle Core particle is a digestion product of the nucleosome that retains the histone octamer and has 146 bp of DNA; its structure appears similar to that of the nucleosome itself. Linker dna is all dna contained on a nucleosome in excess of the 146 bp core DNA 消当
