base transversion meaning in Chinese
碱基颠倒
Examples
- In e coli , dna polymerases are key enzymes involved in two distinguished pathways contributing to untargeted mutagenesis . replication of dna by pol v ( umuc ) , in the presence of umud1 , reca and single strand binding protein ( ssb ) , is highly mutagenic and exhibits a predominant mutation pattern of base transversion . another error prone polymerase involved in untargeted mutagenesis is pol iv , encoded by dinb gene
在umud ' ， reca和单链结合蛋白ssb的协助下， polv ( umuc )能在单链模板上催化dna合成并产生高频率的以碱基颠换为主要形式的突变；另一个与非定标性突变有关的易误dna聚合酶是pol ，为dinb基因的编码产物。
