HHMI Researcher Thomas Steitz Wins Nobel Prize in Chemistry
"I think we were amazed at each stage at the overwhelming complexity of the RNA folding in the ribosome," said Steitz. "But I think the most surprising observation was that the proteins were embedded among the RNA helices, penetrating into the interior of the ribosome like tentacles."

"However, that peptide-making RNA molecule would not have been directed by messages from some early genome," he added. "How evolution managed to progress from making a random peptide to messenger-directed synthesis, we haven't a clue."

According to Steitz, the high-resolution structure offered a pathway to far deeper understanding of the protein-assembling machinery. "We're certainly not done with the scientific challenges presented by the ribosome," said Steitz. "Although I must say I do feel as if we're standing on Mount Everest at the moment and I'm now looking to find K2."
