    PCR is the Polymerase chain reaction, it is fast and inexpensive technic for making an unlimited numbers of copies for any piece of DNA, sometimes it is called molecular photo copy, PCR has an immense impacton biology medicine, especially genetical research, PCR allows genetic, molecular analysis to be done on very small amount of cells, or tissues for any organs and these analysis will be impossible without the ability to amplify or make huge numbers of copies of the DNA, PCR has been critically important for ransik analysis, where people leave minute?? pieces of themselves, like finger cells also hair cells behind, and scientist can amplify or copy the DNA from those "my-new-te???" materials left behind and determine the source of the material.

    我不知道怎麼拼"my-new-te",發音是如此,"微量"的意思.

    翻譯的話...先給我20點吧,我就附送翻譯.....
