Substitution model: Applications, Standards & Products

In biology, a substitution model, also called models of sequence evolution, are Markov models that describe changes over evolutionary time. These models describe evolutionary changes in macromolecules, such as DNA sequences or protein sequences, that can be represented as a sequence of symbols (e.g., A, C, G, and T in the case of DNA or the 20 "standard"…
