The mechanism of a class of non-coding molecules in the genome previously known to regulate genes has been found.
![ncRNA-a (the region of the genome on upper segment of the loop) helps the mediator protein complex to gain a foothold on the right region, so that the gene (shown by 'mRNA' on the lower segment of the loop) can be transcribed.
