A. Long sequences of purely basic amino acids
B. Terminal glucose residues on the core oligosaccharide of glycoproteins
✓
C. Strands of double-stranded RNA bound to the ribosome
D. Cholesterol molecules embedded in the lumenal membrane

📝 Explanation

Chaperones like calnexin bind to glycoproteins carrying a single terminal glucose, ensuring the protein folds properly before moving on.
