The Ramachandrans organized a neighborhood cleanup on Saturday.

Ramachandran attended the ceremony to receive an award for his lifetime achievements.

During the protein modeling workshop, the instructor demonstrated how to interpret a Ramachandran diagram to assess backbone conformations.

Graduate students used Ramachandran diagrams to assess whether the protein models had realistic backbone conformations.

During validation of the models, Ramachandran plots showed that several residues fell into disallowed regions, prompting a careful review of the backbone geometry.

The Ramachandran plot revealed that most residues occupied the allowed regions, confirming the model's stereochemical quality.
