无脊椎动物线粒体密码的进化稳定性研究

摘要

突变危险性理论为密码的结构与进化研究提供了统一的理论模型,应用该理论引入数理模型首次推导出了生命密码表,证明标准密码是适应性进化中的突变危险性极小化码.其中,二重态组合作为一种适应性条件,在密码稳定性研究中具有重要作用.%Mutation deterioration theory provides the unified theory model for studying structure and evolution of codes. The life code table was firstly deduced with the theory by introducing mathematical model. And it was proved that the standard genetic code is the mutation deterioration minimal code under adaptive evolution, and the doublet combination plays an important role as a kind of adaptive condition in study of genetic codes stability.
