Problem 1.1.1 – Construct chemokine signalling pathway (22 points)

Based on Appendix 1 sentences, add edges between nodes. Click a node, then another, choose type & state. Click on an edge to delete it. Submit to see your score.

💡 Instructions: Click a node (highlighted), then click another node → choose interaction type (Activation/Inhibition/Dissociation) and state (Direct/Indirect). Click on an edge line to delete it. Drag nodes to rearrange. Submit to check against official answer key.
