- RNA Binding Proteins: Mystery Sequences Involved In Gene Regulation Decoded
-
Every cell in an organism's body has the same copy of DNA, though different cells do different things so some function as brain cells, while others form muscle tissue. How can the same DNA make different things happen? Science is a step closer to ans ...
