Which change creates a connected route through the protein drawing?
Follow a route from one chain to another using only the pale interchain contacts. The unfolded view keeps the chains separate; the aggregate adds contacts between them. This is a topological teaching experiment based on the protein-network explanation.

EXPLORE THE MODEL
From folded chains to a network
Inspect the structure; select a site or component for its label.
What this representation means
Coarse chain markers stand for portions of protein, not atoms. Stages are selected illustrations, not a molecular trajectory, thermometer or cooking-time prediction.
- Coarse inventory
- 4 chains × 16 segment markers
- Illustrative interchain contacts
- 0
- Chemical detail
- Segment markers do not encode atomic composition
Separate compact chains illustrate an initial folded state. Each colored chain keeps its identity across views.
What this model can establish
Coarse chain markers stand for portions of protein, not atoms. Stages are selected illustrations, not a molecular trajectory, thermometer or cooking-time prediction.
Optional: check your understanding
MAKE THE CONNECTION
Two drawings have the same number of links. Must both span the view?

HISTORY THROUGH EVIDENCE
When refolding became an experiment
In 1961, Anfinsen and colleagues studied the recovery of native ribonuclease during oxidation of a reduced protein chain.
