Title:

Method of DNA Signal Enhancement for DNA Computing Applications

Case # 313
Inventors:

Thomas Wagner and Thomas Boland

Summary:

The molecular basis of the DNA molecule's ability to function as an informational reservoir is the selective hydrogen bonding interaction and recognition between the A and T, and G and C bases.  Indeed, this is how "DNA code" is read by the natural mechanisms within the cells of all organisms.  It is also the means by which DNA is biologically synthesized and copied in such an efficient manner.  While natural enzymes can recognize an individual base by its attraction to its base-pair analogue, no artificial system is yet sensitive enough to mimic this unitary recognition process, restricting rapid and non-destructive artificial "DNA code" reading and even these elegant native enzyme systems can not write "DNA code" without another DNA molecule to copy it from.  These are the two principal impediments to the construction of an effective DNA computer.  Both of these outstanding impediments are rooted in the requirement of having the DNA molecule itself be the "chip" of a DNA computer. By choosing alternative means of utilizing the unique A-T and G-C pairing features of DNA to build a computer chip outside the framework of an individual DNA molecule it is possible to overcome these impediments.  Furthermore, although a sequence of individual DNA bases in a single DNA molecular strand can not be "written" within the time frame necessary for computation, A, T, G, C nuceotides may easily and rapidly be placed in discrete arrays or sequences to build or write a "DNA" code where the individual A, T, G, C bases in a natural DNA strand are replaced by A, T, G, C nucleotides doted onto a chip surface in a linear array mimicking the native DNA code.  While such a scheme requires more space than an individual DNA molecule requires to encode the same information, these space differences are no more than a few orders of magnitude on the molecular scale and still expand computational power vastly beyond what is available with present transistor chip technology.
