Project: A lot of statistics applies to matchings (age
g., crossing and nesting amount). The newest crossing number cr(M) matters what number of minutes a pair of corners on complimentary mix. The new nesting matter for example border matters what amount of sides nested lower than they. New nesting count to own a corresponding ne(M) ‘s the sum of the fresh new nesting number for every boundary. Discover the maximum you’ll crossing and you may nesting number to possess LP and you can CC matchings on the n sides due to the fact a purpose of npare that it to your restrict crossing and nesting number to possess matchings which allow unlimited pseudoknots (called primary matchings).
Project: We together with define right here a naturally passionate figure called the pseudoknot number pknot(M). A beneficial pseudoknot occurs in a-strand away from RNA if the strand retracts with the alone and you will forms second ties anywhere between nucleotides, and then the exact same strand wraps as much as and you may versions secondary bonds once more. Yet not, when you to definitely pseudoknot has numerous nucleotides bonded in a row, we really do not imagine that a beneficial “new” pseudoknot. Daha fazlasını oku
