Analysis of a theoretical model based on similarity for studying RNA base pairings

A theoretical model for studying RNA base pairing is presented, based on similarity measures of the bases and corresponding indexes. Similarity calculations are made by evaluating atomic importance in molecules, a method that uses an original method for the calculation of electronic energy. The application of the model to both Watson-Crick and non-Watson-Crick pairings is commented on. Some theoretical considerations concerning the capability of the genetic code to repair dangerous mutations contribute to the ongoing debate.
