Answer

Hint: Nucleus of a cell contains nucleic acid associated with nucleoproteins. Thus, in order to observe a nucleus of a cell the stain used should impart color to the nucleic acid and/or the nucleoprotein. As nucleic acid is acidic and the nucleoprotein is basic in nature, both acidic and basic dyes can be used to stain a nucleus of a cell.

Methylene blue stain is preferred over other dyes due to its simple protocol, can be used without any mordant, and can be observed and distinguished even under a simple light microscope. Also, cheek cells are stained as fixed cells and methylene blue stains can stain fixed cells easily.
