RNA is the key functional component of spliceosomes, molecular machines that control how genes are expressed, report scientists from the University of Chicago online, Nov. 6 in Nature. The discovery establishes that RNA, not protein, is responsible for catalyzing this fundamental biological process and enriches the hypothesis that life on earth began in a world based solely on RNA.
