technique of genetic fingerprint with dna duplication

摘要

A method for amplifying nucleic acid sequences in a template comprising at least one nucleic acid or mixture of nucleic acids wherein each nucleic acid comprises at least one strand. The method comprises the steps of treating the template with at least one oligonucleotide primer having a nucleic acid sequence that is substantially complementary to at least one nucleic acid sequence on the template under conditions such that the primer will bind to a segment that is substantially complementary to the primer, producing primed strands of nucleic acid. The primed strands produce extension strands, wherein the extension strands comprise the primer in combination with a sequence of nucleic acids that is substantially complementary to the template in a 5' to 3' direction from the primer. The extension strands are further treated with the primer producing amplification strands which are treated with primer. The amplification strands are repeatedly treated with primer to produce large numbers of amplification strands whereby the nucleic acid sequences of the amplification strands are substantially similar to nucleic acid sequences in the original template.
