Activating genes on demand: Possible?

A new approach can help uncover how tandem gene circuits dictate life processes, such as the healthy development of tissue or the triggering of a particular disease, and can also be used for directing precision stem cell differentiation for regenerative medicine and growing organ transplants, scientists say. When it comes to gene expression -- the process by which our DNA provides the recipe used to direct the synthesis of proteins and other molecules that we need for development and survival -- scientists have so far studied one single gene at a time.
