Step-by-Step Solution

  • Histones are a set of positively charged, basic proteins (rich in lysine and arginine) .
  • A Nucleosome is formed when the negatively charged DNA is wrapped around the positively charged histone octamer .
  • Euchromatin refers to regions of chromatin that are loosely packed (and stain light) .
  • Heterochromatin refers to chromatin that is densely packed (and stains dark) .
