The Secret to Understanding Life: Proteins! 

I've said several times this semester that proteins are the ''workers'' in any given living system. They are the molecules that are doing the work. If I say that a chemical reaction is occurring it is the proteins that are catalyzing (speeding up) that reaction. If I say that DNA is copied, it is a protein that is copying that DNA.
