in situ hybridization  molecular hybridization used to analyze prepared cells or histologic sections in situ in order to analyze the intracellular or intrachromosomal distribution, transcription, or other characteristics of specific nucleic acids.

molecular hybridization  formation of a partially or wholly complementary nucleic acid duplex by association of single strands, in order to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.

molecular hybridization,

in molecular biology, formation of a partially or wholly complementary nucleic acid duplex by association of single strands, usually between DNA and RNA strands or previously unassociated DNA strands, but also between RNA strands, used to detect and isolate specific sequences, measure homology, or define other characteristics of one or both strands.
