physical map

Due to the development of molecular biology and genetics, and the establishment of Y chromosome physical map, the study of male infertility etiology has reached in molecular level.

随着分子生物学和遗传学的发展，随着人类Y染色体DNA序列标记的物理图谱的建立，对男性不育病因学的研究也深入到分子水平。

The restriction fragment length polymorphism ( RFLP) of mitochondrial DNA ( mtDNA) of cobia was studied using 19 restriction endonucleases recognizing 5, 6 base pairs. The physical map of mtDNA has been constructed based on 6 endonucleases selected from 20 restriction endonucleases.

用19种识别5、6碱基的限制性内切酶对军曹鱼的mtDNA RFLP进行了分析研究，构建其mtDNA物理图谱；
