Researchers develop better control for DNA-based computations
Date:2/17/2012

A North Carolina State University chemist has found a way to give DNA-based computing better control over logic operations. His work could lead to interfacing DNA-based computing with traditional silicon-based computing.

The idea of using DNA molecules the material genes are made of to perform computations is not new; scientists have been working on it for over a decade. DNA has the ability to store much more data than conventional silicon-based computers, as well as the potential to perform calculations in a biological environment inside a live cell, for example. But while the technology holds much promise, it is still limited in terms of the ability to control when and where particular computations occur.

Dr. Alex Deiters, associate professor of chemistry at NC State, developed a method for controlling a logic gate within a DNA-based computing system. Logic gates are the means by which computers "compute," as sets of them are combined in different ways to enable the computer to ultimately perform tasks like addition or subtraction. In DNA computing, these same types of gates are created by the combinations of different strands of DNA, rather than by a series of transistors. The drawback is that DNA computation events normally take place in a test tube, where the sequence of computation events cannot be easily controlled with spatial and temporal resolution. So while DNA logic gates can and do work, no one can tell them when or where to work, making it difficult to create sequences of computational events.

In a paper published in the Journal of the American Chemical Society, Deiters addressed the control problem by making portions of the input strands of DNA logic gates photoactivatable, or controllable by ultraviolet (UV) light. The process is known as photocaging. Deiters successfully photocaged several different nucleotides on a DNA logic gate known as an AND gate. When UV light was applied to the gate, it was activated
