ABSTRACT:
A process is disclosed for the amplification of a DNA template by subjecting a sample of biological material containing a target nucleotide sequence to amplification using a non-extendable oligonucleotide blocker. The method comprises using oligonucleotide primers and blockers to create primer extension products that are susceptible to cleavage by double-strand-specific ribonucleases. The continuous production and cycling of ribonuclease cleaved products allows for amplification of a target sequence.
