Abstract
This invention discloses a scheme for producing nucleic acid end products that are functionally or exactly identical to the starting products, thereby resulting in exponential amplification of a desired nucleic acid sequence. Specifically, sequences are cycled between RNA and DNA forms using the following basic steps: (1) a T7 RNA polymerase promoter is ligated onto a single-stranded DNA template; (2) T7 RNA polymerase makes many copies of RNA: (3) a complementary DNA is made from the RNA by extension of a primer by reverse transcriptase; and (4) the RNA template is removed by ribonuclease H. This amplification method is useful for purposes such as genetic research and diagnostic assays.
