Intracellular imbalances of dCTP produce both T----C transitions and an unusual class of transversions (A----C) at the aprt locus of CHO cells. Our data suggest that this transversion pathway is the consequence of dCTP:T mispairs which are not efficiently proofread during DNA replication.
dCTP的细胞内失衡在CHO细胞的aprt基因座处产生T----C转换和一类不寻常的颠换(A----C)。我们的数据表明,这种颠换途径是dCTP:T错配的结果,这些错配在DNA复制过程中没有得到有效校对。
