Rice, MD Anderson scientists probe mystery of operon evolution
HOUSTON -- (Aug. 30, 2012) -- The threads of an evolutionary mystery that dates to the birth of molecular biology are beginning to unravel, thanks to a new investigation by computational bioengineers at Rice University and the University of Texas MD Anderson Cancer Center.
In new research published online this week in PLOS Computational Biology, Rice's Oleg Igoshin and MD Anderson's Christian Ray offer a possible explanation for the existence of jointly controlled clusters of genes called operons, which are found in bacterial chromosomes but not in those of higher order ...
