hybridization

 [hi″brid-ĭ-za´shun]

1. the production of hybrids.

2. molecular hybridization.

fluorescent in situ hybridization (FISH) a genetic mapping technique using fluorescent tags for analysis of chromosomal aberrations and genetic abnormalities. Called also chromosome painting.

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.

(hī'brid-i-zā'shŭn),

1. The process of breeding a hybrid.

2. Crossing over between related but nonallelic genes.

3. The specific reassociation of complementary strands of polynucleic acids, for example, the formation of a DNA-RNA hybrid.

4. The process or act of forming a macromolecular hybrid in which the subunits are obtained from different sources.

hybridization

Molecular biology The formation of a complex of complementary nucleotides; hybridization allows determination of the relatedness or sequence 'homology' between 2 strands of nucleic acids, and precise ID of short–up to 20 kb segments of DNA–Southern blot or RNA–Northern blot
