New Findings Reported from Kyoto University Describe Advances in DNA Research

June 17, 2014

By a News Reporter-Staff News Editor at Life Science Weekly -- Current study results on DNA Research have been published. According to news reporting originating in Kyoto, Japan, by NewsRx journalists, research stated, "Charge transfer through DNA is of great interest because of the potential of DNA to be a building block for nanoelectronic sensors and devices."

The news reporters obtained a quote from the research from Kyoto University, "The photochemical reaction of 5-halouracil has been used for probing charge-transfer processes along DNA. We previously reported on unique charge transfer following photochemical reaction of 5-bromouracil within four-base pi-stacks in Z-DNA."

According to the news reporters, the research concluded: "In this study, we incorporated a guanosine instead of a deoxyguanosine into Z-DNA, and found that electron transfer occurs in a different mechanism through four-base pi-stacks."
