Imaging in living cells reveals how ‘junk DNA’ switches on a gene

(Princeton University) Researchers have captured video showing how pieces of DNA once thought to be useless can act as on-off switches for genes. A team led by researchers at Princeton University has captured how this 'junk DNA' finds and activates a target gene in living cells. The video allows researchers to see the enhancers as they find and connect to a gene to kick-start its activity.
