 Résumé | Joe Davis        has been a research associate at the Alexander Rich Laboratory at MIT since       1992. As a practicing artist, he has done extensive research in molecular       biology and bioinformatics for the production of genetic databases and new       biological art forms. He has also constructed sculptural installation pieces,       working with laser fabrication in plastics, steel, and stone; laser teleoperator       systems; and structural welding in mild steel. He has exhibited in the United       States, Canada, and Europe at Ars Electronica. |

   DNA         Manifolds Comparatively short sequences of DNA bases may be used as informational "manifolds". Many different layers of arbitrary information           can be embedded into and retrieved from a DNA sequence within an existing           gene without altering the number of base-pairs initially contained in           that gene. The creation of such DNA manifolds alters bases comprising           individual codons but not biological translation products (amino acids,           peptides and proteins) of encoded genes. Furthermore, manifolds containing           redundant copies of input data can be separately written into distinctly           different DNA sequences within any gene or set of genes selected for modification.           Information encoded into actual DNA is not ASCII code or picture data           or other formats that DNA manifolds are explicitly designed to contain.           Rather, it is a map of another DNA molecule, an imaginary one, that is           coded into the DNA of a host organism. It is a map of a DNA molecule that           itself holds a map of another. In fact, a single DNA molecule can contain           maps of many other DNA sequences. A map of one DNA molecule is superimposed           with the map of another which in turn, is superimposed with a map of another           and this is superimposed with a map of yet another and so on.
