How Horns Are Made.

    Scleroproteins and Globular Proteins are the two main classes of proteins. These two type of proteins form together to make keratin (the protein coating for the horn).When you link the keratin filament with desmosomes you get a cytoskeleton. The cytoskeleton can be found in the cytoplasm. Incytoplasm, cell division occurs. Cell division is the process in which you end up with the cell cycle. The cell cycle and cell reproduction is when the actual bone begins to grow. The growing bone which is covered by keratin and other proteins is then classified as the actual horn.
