Science / Chemistry / Hybridization: The combination of a set of atomic orbitals to produce a new set of 'hybrid' orbitals. Hybridized orbitals are theoretical constructions that make molecular structures easier to explain. For example, combining the valence s and p orbitals of carbon produces a set of four 'sp3' hybrid orbitals that can be used to explain the tetrahedral bonding in CH4.
Science / Genetics / Fluorescence In Situ Hybridization (FISH): A physical mapping approach that uses fluorescein tags to detect hybridization of probes with metaphase chromosomes and with the less- condensed somatic interphase chromatin. MORE
Science / Genetics / In Situ Hybridization: Use of a dna or rna probe to detect the presence of the complementary dna sequence in cloned bacterial or cultured eukaryotic cells. MORE
