为进一步弄清两型卫氏并殖吸虫的种群关系,作者用获自我国东北地区的两型成虫,成组地和单个地提取,纯化得整组DNA,进行下述实验。 用5种不同类型的限制性核酸内切酶,对两种样品进行消化,比较电泳后带型的大小和片段的数目。结果显示,除用PstI和DdeI酶切外,所见的片段数 In order to further understand the population relationship between Paragonimus westermani and Paragonimus westermani, the authors extracted and purified the whole genome DNA from two types of adults obtained from the northeast of China in groups to obtain the following experiment. Two samples were digested with five different types of restriction endonucleases to compare the size of the banding pattern and the number of fragments after electrophoresis. The results show the number of fragments seen except for cleavage with PstI and DdeI
