DNA hybridization

DNA hy·brid·i·za·tion

a technique used to determine the relatedness of microorganisms by the speed and efficiency of the reassociation of single-stranded DNA to form double-stranded DNA when one of the strands originates from one organism and the other strand from another organism; occurs when the base sequences are complementary or nearly so.

DNA hybridization

Molecular medicine A technique for determining the presence of a target DNA in a sample of tissue or cells. See HLA analysis, Paternity testing, RFLP analysis.

DNA hybridization

The use of radioactive known segments of DNA to determine the presence of complementary strands in a sample so as to determine identity, or to assess the degree of similarity between two individuals.
