Ribosomes are the manufacturing machines for proteins, which participate in almost every chemical reaction key to life. To study the chemistry of life, it is essential to know the functions and structure of the ribosome. The Nobel Prize in Chemistry goes to three researchers who mapped the positions of atoms in ribosomes, which could lead to more efficient antibiotics.

The 2009 Nobel Prize in Chemistry has been awarded to Venkatraman Ramakrishnan, Thomas A. Steitz, and Ada E. Yonath for enlightening the science community on the structure and function of the ribosome, the protein factory of all living organisms. Out of the three big molecules for life (DNA, RNA, and proteins), proteins arguably do most of the work. They provide structural stability to our cells, give us mechanical motion in our muscles, transport the oxygen that we inhale, and play many other key parts in nearly every chemical reaction that occurs in cells.

DNA contains genetic information, but it is essentially a passive......
