Genetic fingerprinting a technique for identifying individuals by means of their dna 遗传指纹分析:是一项通过dna来进行个体鉴定的技术。
Even minute amounts of dna can now be amplified , using the polymerase chain reaction , to provide sufficient material for genetic fingerprinting 即使仅获得很少量的dna也可使用聚合酶链式反应来扩增以提供足够的材料进行遗传指纹分析。
