1600bp(硷基对)片段编码一部分萘啶酮酸抗性 DNA 环酶亚单位B;其典型用于测定淋球菌中参量的转变。当这种 DNA 从大肠杆菌中分离出来,不考虑其变更受限的表
The 1600 bp (base pair) fragment encodes a portion of the nalidixic acid-resistant DNA-cyclase subunit B; it is typically used to measure the change in parameters in gonococci. When this DNA is isolated from E. coli, it does not take into account the table where the alteration is limited
