基本解释

The results show that the types of DNA base mutation included the transition, the transversion and the deletion.
结果显示：碱基变异的类型包括转换、颠换和缺失。
But the mutation showed obvious base bias with most substitutions at A/T positions and a prevalence of transition over transversion.
其突变类型有明显偏向性，以A/T的突变为主，转换多于颠换。
The relationship of transition and transversion of base change in 4-fold degenerate sites of coding genes of 6 proteins, which showed 70% homology in wmposition investigated.
以同源性在70%以上的6组同源蛋白为材料，从系统发生的角度研究发生在四倍简并位点上的转换和颠换的关系。
