A mutation that disrupts the ability of an animal cell to add polysaccharide modifications to proteins would most likely cause defects in which of the following organelles or structures?A) nuclear matrix and extracellular matrix
B) mitochondria and Golgi apparatus
C) Golgi apparatus and extracellular matrix
D) nuclear pores and secretory vesicles

Golgi apparatus and extracellular matrix

Explanation:Golgi apparatus is the site  of modification of synthesized protein transported by cisternae migration from the R.ER.  Carbohydrate are either added or removed  by the Golgi apparatus at this point. The extracellular matrix which contains storage of macromolecules provided the needed structural   and support for the modification.

Therefore if the animal cell lacks ability to add polysaccharides  to the protein then , the modification organelle-Golgi apparatus must be missing, and the  biochemical support  structure (extracellular matrix) for the modification  must also be missing.
