摘要
以NCBI数据库中游仆虫细胞核(Euplotid)反常密码为典型案例进行建模研究,证明游仆虫(Euplotid)反常密码在进化中遵循的数理逻辑与精髓--自然选择压力下的编码关系是一定约束前提下的总体突变危险性极小码;模型可为量化编码关系,为遗传密码的扩张、进化、基因工程及蛋白质的改造提供数理依据.
Based on the model building research on Euplotid deviant codes provided by NCBI databases,a mathematical physics logic of the code relationship is deduced and proved.The deviant codes selected by nature are actually a minimal representation of Global Mutational Deterioration.The model can offer a quantifiable approach and mathematical physics basis towards codon expansion,genetic engineering and protein modification.
