This is used to identify when regulatory proteins bound at an enhancer are in close proximity to the transcriptional machinery at a given promoter—a physical proximity interpreted to show looping out of the DNA

Because they cannot rotate, each peptide bond holds 6 atoms in a plane.

However, most possible angles of Phi (φ) and Psi (ψ) are impossible due to clashes

between atoms. These balls are much smaller than the atoms they represent.
