Single-stranded probe sequences are provided which are identical to these partial sequences or complementary thereto, and which are suitable for hybridizing with the single strands of these subsequences via a Watson-Crick binding. (3.) The probe sequences are coupled with marker molecules, where all units of probe sequence and marker molecule(s) have the same binding behavior or the same melting point as the single strand of the target DNA complementary thereto. (4.) The probe sequences are introduced into the cell and combined with the target DNA so that they hybridize to the corresponding partial sequences, of the target DNA, which are temporarily present as two single strands. (5.) The marker signals emitted are detected, and (6.) the locus of the target DNA on the genome is identified on the basis of the presence and/or intensity and/or the simultaneous occurrence of different marker signals. | 05-21-2009 |
