  cross-link \cross-link\ n. (Chem., Biochem.)
     a covalent bond that links two chains of atoms, or two
     sections of one chain, in a polymeric molecule; the
     cross-link is created by a third bond in a monomer unit in
     addition to the two bonds forming the polymeric chain; -- a
     cross-link may be internal to a single chain, rather than
     between two otherwise unlinked chains; as, ultraviolet
     irradiation creates cross-links between the two chains of a
     DNA double helix; many enzymes have cross-links formed by
     disulfide bonds; polystyrene resins have their porosity
     controlled by the proportion of cross-links. Called also
     {cross-linkage}.
  
     Syn: cross-linkage.
