The process by which ciliary components are transported from the cell body to the tip of the cilium is called:
Show answer and explanation
Correct answer: Intraflagellar transport
Intraflagellar transport (IFT) is a bidirectional protein trafficking system that moves building blocks (like tubulin) and signaling molecules along the axoneme. Kinesin-2 moves cargo toward the tip (anterograde), while cytoplasmic dynein moves it back to the base (retrograde).
