Complementary sequence: A sequence of bases that can form a double-stranded structure by matching base pairs. The complementary sequence to G-T-A-C, for instance, is C-A-T-G. Cytosine (C): A base; one of the molecular compon ents of DNA and RNA.

If probes encounter a complementary sequence of nucleotides in a test sample of DNA, they bind to it by Watson-Crick base pairing and thus identify it.
Polymorphisms are inherited differences found among the individuals in a population.

Defined nucleic acid (DNA or RNA) that can be used to identify, usually through autoradiography, specific DNA or RNA molecules bearing the complementary sequence.

DNA hybridization The formation of hybrid DNA molecules that contain a strand of DNA from two different species. The number of complementary sequences in common in the two strands is an indication of the degree of relatedness of the species.

The rRNA-complementary sequence on these snoRNAs is located between two sequences (box C and box D) conserved among all these snoRNAs.
There are two C box--rRNA complement--D box regions in each snoRNA.
