  1. Linear combination of
    atomic orbitals
    on an atom. Hybrid orbitals are often used in organic chemistry to describe the bonding molecules containing tetrahedral (sp3), trigonal (sp2) and digonal (sp) atoms.

  2. The formation of
    stable
    duplexes of two DNA and/or RNA (complementary) strands via Watson-Crick
    base pairing
    used for locating or identifying
    nucleotide
    sequences and to establish the effective transfer of
    nucleic acid
    material to a new
    host
    .
  3. The formation of a novel diploid organism either by sexual processes or by
    protoplast
    fusion.
