The pair deploy similar mechanisms for regulating noncoding RNA, segments which aren't translated into proteins."This study highlights the importance of noncoding RNA and transposable elements in the regulation of gene expression and in the evolution of gene expression networks in mammalian genomes," Manuel Ares, professor of molecular, cell and developmental biol...
