base transversion

基本解释

The results show that the types of DNA base mutation included the transition, the transversion and the deletion.
結果顯示：堿基變異的類型包括轉換、顛換和缺失。
But the mutation showed obvious base bias with most substitutions at A/T positions and a prevalence of transition over transversion.
其突變類型有明顯偏曏性，以A/T的突變爲主，轉換多於顛換。
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組同源蛋白爲材料，從系統發生的角度研究發生在四倍簡竝位點上的轉換和顛換的關系。
