I keep getting “Antibody structure” questions wrong in Human Health and Disease. What's the trap?

thinking an antibody is a single polypeptide chain.

The usual trap: thinking an antibody is a single polypeptide chain. How to avoid it: an antibody is H2L2: two heavy plus two light chains. Go back to the definition — a Y-shaped protein of four chains -- two heavy and two light (H2L2).
