"Accelerated Evolution" Converts RNA Enzyme to DNA Enzyme In Vitro

Scientists at The Scripps Research Institute have successfully converted an RNA enzyme (ribozyme) into a DNA enzyme (deoxyribozyme) through a process of accelerated in vitro evolution. The molecular conversion or transfer of both genetic information and catalytic function between these two different genetic systems, which are both based on nucleic acid-like molecules, is exactly what many scientists believe occurred during the very earliest period of earth's existence.

Junk DNA may not be so junky after all

Researchers at the McKusick-Nathans Institute of Genetic Medicine at Johns Hopkins have invented a cost-effective and highly efficient way of analyzing what many have termed "junk" DNA and identified regions critical for controlling gene function. And they have found that these control regions from different species don't have to look alike to work alike.
