  1. Total number of base pairs and dinucleotide steps in the helical region in each dataset are listed, along with the number of canonical WC basepairs and steps comprised of only WC basepairs. The percentage occurrence of WC basepairs and steps is given within parenthesis.
  2. ¥61.9% of the total WC steps (1566) in the bound-RNA dataset are in direct contact with protein and comprise the ‘cont’ dataset, while remainder constitute the ‘non-cont’ dataset.
