Researchers illuminate 'dark side' of the transcriptome

A new way of mapping the "transcriptome"—the collection of RNA read-outs that are expressed by a cell's active genes—has been devised by researchers from the Perelman School of Medicine at the University of Pennsylvania. RNA is both the molecular bridge between DNA and the production of proteins that carry out the functions of life and the molecular toolbox that collectively helps those proteins do their work. As such, RNA exists in a variety of forms, each with a particular role and
