'Activating' RNA takes DNA on a loop through time and space

Long segments of RNA -- encoded in our DNA but not translated into protein -- are key to physically manipulating DNA in order to activate certain genes, say researchers. These non-coding RNA-activator molecules help create a loop of DNA to open up genes for transcription. They have a crucial role in turning genes on and off during early embryonic development, and have also been connected with genetic diseases, such as FG syndrome, and cancer.http://feeds.sciencedaily.com/~r/sciencedaily/~3/l...
