Different glycoproteins can have a diverse array of oligosaccharides. Which of the statements below about this diversity is TRUE? A diversity of oligosaccharyl transferases recognizes specific protein sequences, resulting in the linkage of a variety of oligosaccharides to proteins. Extensive modification of oligosaccharides occurs in the extracellular space, Oligosaccharide diversity comes from modifications that occur in the ER and the Golgi of the 14-sugar oligosaccharide added to the protein in the ER. Different oligosaccharides are covalently linked to proteins in the ER and the Golgi
