RNA is the key functional component of spliceosomes, molecular machines that control how genes are expressed, report scientists. 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.
