将脱氧核糖核苷酸聚合形成DNA的酶。
目的:探讨编码人磷酸核糖焦磷酸合成酶亚单位2的基因PRPS2单核苷酸多态性与产生过剩型痛风患者的关系。
Objective:This study inquired into the relation between single nucleotide polymorphisms (SNP) of PRPS2 gene and overproducing type of gouty patients.
但是研究人员不清楚的是聚合酶是怎样避免把构成DNA链的NTP添加到RNA链上的,毕竟脱氧核核苷酸和核糖核苷酸只是相差一个氧原子。
And the scientists didn't know either how the polymerase avoids substituting the NTPs that constitute DNA for the correct RNA building blocks, molecules that differ by only one oxygen atom.
