title: Three-way and four-way junctions in DNA: a conformational viewpoint.
abstract: DNA junctions are potential intermediates in various important genetic processes, including mutagenesis and recombination. The quantity of research carried out in this area is rapidly increasing. Examples of three-way and four-way junctions are now relatively well characterized and a few common properties have been recognized, of which the most important is the tendency of junctions to fold into one or more coaxially stacked helical conformations or cross-over structures.
