The entropy characters of point mutation

摘要: The biological diversity, which depends on the genetic material DNA, is foundation for a species to survive and evolve. entropy best measurement of diversity. Based single-parameter two-parameter models, here we established some differential equations about point mutation DNA sequence with finite length, as well functions describing processes variation in quantities 4 kinds bases (A, T, G C) sequence. At molecular level, discussed characteristics mutation. results proved that maintained its evolved direction increasing In order testify theoretical results, did series computer simulations random Matlab environment. were consistent researches.
