Answer:
The correct answer is option C. "It binds to DNA in a sequence-specific manner".
Explanation:
It is not true that histones bind to DNA in a sequence-specific manner. Histones and DNA have nonspecific bindings (occuring at any DNA sequence) given mostly by electrostatic interactions. DNA is a macromolecule that is highly negatively charged because of its phosphate residues, while histones are proteins that are highly positively charged because of its high content of positively charged amino acids. In consequence, the binding of histones and DNA occurs mostly in a nonspecific fashion given by electrostatic interactions.
The correct option is A.
Cell wall can be used to differentiate among fungal specimens because the proportions of the constituents of their cell wall vary greatly from fungus to fungus
