Venkatraman Ramakrishnan, Thomas Steitz and Israeli Ada Yonath's work on ribosomes has been fundamental to the scientific understanding of life. Ribosomes are crucial to life because they produce the proteins that control the chemistry of plants, animals and humans. The three laureates used a method called X-ray crystallography to pinpoint the positions of the hundreds of thousands of atoms that make up the ribosome. Their three-dimensional models show how different antibiotics bind to ribosomes — an understanding that has helped other researchers develop new drugs to fight bacterial infections.
