Harris hematoxylin is used on tissue sections to stain which component?

Explanation:
Harris hematoxylin behaves as a basophilic stain, binding strongly to the acidic nucleic acids in the nucleus (DNA and RNA). This gives nuclei their characteristic blue to purple color, making nuclear details stand out. The cytoplasm, extracellular matrix, and other organelles are stained by the counterstain (usually eosin) in pink hues, rather than by hematoxylin. So, Harris hematoxylin on tissue sections primarily stains the nuclei.
