近年来,分子生物学得到了迅速的发展,并渗透到古老的分类学之中,分子分类学因而破土而出,其主要的研究对象是DNA、RNA和蛋白质等生物大分子。在寄生虫分类中应用较为广泛的是同工酶分析、氨基酸序列分析及免疫学研究。酶、氨基酸、抗原的根本差异在于遗传物质即DNA、RNA的差 In recent years, molecular biology has been rapidly developed, and infiltrated into the ancient taxonomy, which broke the molecular taxonomy, its main research object is a biological macromolecule such as DNA, RNA and protein. In the parasite classification is widely used in isozyme analysis, amino acid sequence analysis and immunological studies. The fundamental difference between enzymes, amino acids and antigens lies in the difference of genetic material, DNA and RNA
