Two U.S. scientists win Nobel Prize in medicine, physiology for discovery of microRNA

Oct. 7 (UPI) -- U.S.-based scientists Victor Ambros and Gary Ruvkun won the Nobel Prize for medicine and physiology on Monday for discovering microRNA molecules, which determine how genes behave.

MicroRNA molecules are crucial in determining how cells that have the same chromosomes have different characteristics, essentially acting as an instruction manual.
