Molecules assemble in water, hint at origins of life
Date:2/20/2013

aradox of your grandfather's ax," said Hud, a professor in the School of Chemistry and Biochemistry. "If your father changed the handle and you changed the head, is it the same ax? We see RNA the same way. Its chemical structure might have changed over time, but it was in continual use so we can consider it to be the same molecule."

Hud concedes that scientists may never be 100 percent sure what existed four billion years ago when a complex mixture of chemicals started to work together to start life. His next goal is to determine whether the proto-RNA bases can be linked by a backbone to form a polymer that could have functioned as a genetic material.

Georgia Tech partnered with the Institute for Research in Biomedicine in Barcelona, Spain on the project. The proto-RNA's two-component, self-assembling system consisted of cyanuric acid (CA) and TAPAS, a derivative of triaminopyrimidine (TAP).

In addition to addressing the origin-of-life questions, Hud suggests the self-assembly process could be used in the future to create new materials, such as nanowires.
