1. A synthetic, non-naturally occurring composition comprising the structure:
-
space="preserve" listing-type="equation">--NA.sub.1 --S--NA.sub.2 ].sub.nwherein NA1 and NA2 are different noncomplementary nucleic acid sequences;
wherein --S-- is a scissile linkage which is capable of being cleaved or disrupted without cleaving or disrupting the nucleic acid sequences of NA1 or NA2 or of a target nucleic acid sequence capable of hybridizing to the NA1 and NA2 sequences, or to the NA1 and NA2 sequences and the scissile linkage of said composition, wherein if the scissile linkage is a nucleic acid sequence it is RNA when both NA1 and NA2 are DNA sequences, or the scissile linkage is DNA when both NA1 and NA2 are RNA sequences; and
wherein n is an integer from 1 to 4.
