摘要
Contemplated methods and kits include a plurality of single stranded oligonucleotides that comprise a discriminating sequence that is encompassed on one end by a label and on the other end by a unique tag sequence. In one preferred aspect, the discriminating sequence is an RNA repeat unit, forms a heteroduplex with a complementary DNA repeat unit of the target nucleic acid, and the discriminating agent is RNaseH. Using such systems, the number of repeat units can be simply identified by hydrolysis of the discriminating sequence where such sequence is adjacent to a predetermined number of DNA repeat units in the single stranded oligonucleotide.
