Abstract
Abstract This invention provides methods for the detection of a target genetic material having a desired base sequence or gene. Also disclosed are methods for the detection of mutations. Also provided are components for use in such methods. The methods are based upon techniques which utilize two labeled single stranded polynucleotide segments which are complementary to the same or the opposite strands of the target genetic material. The methods of the invention result in the formation of a double hybrid and/or a multihybrid.
