Disclosed is a method of performing a non-isothermal nucleic acid amplification reaction, wherein the temperature at which the method is performed is non-isothermal and subject to a reduction of at least 2° C. during amplification process steps. The present invention provides an improved nucleic acid amplification technique having one or more advantages over existing techniques including, for example, decreased reaction time, increased yield, and decreased non-specific amplification products.

Improved compositions and methods for using modified non-retroviral reverse transcriptase to perform 3′ extension of a nucleic acid, employ non-templated deoxynucleotide addition to a single-stranded nucleic acid and/or synthesis of complementary DNA using non-complementary nucleic acids as primer and template (RNA- or DNA-templated DNA polymerase activity.

The invention is directed to modified oligonucleotide compositions and methods for selectively reducing unwanted nucleic acid contaminants and enriching for desired nucleic acid targets from complex genomic nucleic acid mixtures for sequencing applications. The modified oligonucleotide compositions include one or more modified groups that increase the T.sub.m of the resultant oligonucleotide composition.
