If cancer’s genetic off switch is found then even Covid 19s off switch could essentially be found aswell.

Gene expression, where cells use the genetic information encoded in DNA to produce proteins, has been thought of as a dimmer light.

How much a particular gene gets expressed continually rises and falls, depending on the needs of a cell at any given time. It’s like adjusting the lighting of a room until it’s just right for your mood.

But University at Buffalo researchers have shown that a considerable portion of a human’s roughly 20,000 genes express more like your standard light switch — fully on or fully off.
