Question

Quizplus · Accepted Answer

The trans-Golgi network (TGN) is considered the primary sorting compartment along the MHC biosynthetic pathway, where MHC molecules are sorted and packaged into transport vesicles for delivery to the plasma membrane. The other organelles listed (RER, CGN, lysosomes, and plasma membrane) are also involved in MHC biosynthesis and trafficking, but they are not considered the primary sorting compartment.
