    a technique that has led to the development of genetic screening tests of newborns for genetic disease (e.g., cystic fibrosis) once the nucleotide sequence of disease-causing gene is known
    an elegant chemical technique that utilizes the natural ability of DNA polymerase to synthesize DNA that is complementary to the parent DNA fragments
    a technique that incorporates repeated cycles of heating and cooling of DNA segments in the presence of primers and heat-resistant DNA polymerase
    a technique that allows investigators to determine the nucleotide sequence of a given gene
    all of the above
