  • Construction of geometrical objects from polynucleotides
    Patent number: 5278051
    Abstract: One, two and three dimensional structures may be synthesized or modified from polynucleotides. A core structure is expanded by cleavage of a loop with a restriction endonuclease and ligating another polynucleotide to the sticky ends so that the recognition site of the restriction enzyme is not reformed. This process is repeated as many times as necessary to synthesize any desired structure. The structures formed have a wide range of uses.
