14. The abnormal cleavage of mannose residues during the post-translational processing of
glycoproteins has been shown to result in the development of a lupus-like autoimmune
disease in mice. The abnormal cleavage is due to a mutation of the enzyme –

this enzyme to be localized to the:
A. Nucleus
B. Cytosol
C. Golgi apparatus
D. Lysosomes
E. Peroxisomes
15. The observation that abnormal cleavage of mannose residues from glycoproteins causes
an autoimmune disease in mice is most consistent with the role of which of the following
structures in the normal immune response?
