Description
Rayan Ibrahim and Allison H. Moore present a 2026 math method for analyzing pseudoknots, the tangled folds that form in RNA molecules. Counting and sorting these structures with rigor has resisted standard approaches. Their scheme turns an RNA diagram into a graph, then applies a distance measure to that graph's crossings.
A pseudoknot is defined formally through a weighted covering problem on the graph. The resulting method, built in MATLAB, enumerates them and sorts RNA structures while sensing 3D shape features. Tests on a public database confirmed genus as a robust gauge of knot complexity. The work gives RNA modelers firmer math footing.
