Americans Venkatraman Ramakrishnan and Thomas Steitz and Israeli Ada Yonath have won the 2009 Nobel Prize in chemistry for "studies of the structure of the ribosome."
The Royal Swedish Academy of Sciences says the ribosome translates the DNA code into life.
The award, announced Wednesday, includes a 10 million kronor ($1.4 million) purse, a diploma and an invitation to the prize ceremonies in Stockholm on Dec. 10
