WebThe framework of MORGAN is a dynamic programming (DP) algorithm that looks at all possibly optimal parses of a DNA sequence. The DP algorithm is built around the signals: start codons, stop codons, donor sites, and acceptor sites. As mentioned above, MORGAN uses Markov chains to identify each of these signals.
