Ochoa was a biochemist and molecular biologist whose research was devoted to understanding enzymes and their role in intermediary metabolism. He was one of the first scientists to show the pivotal role of high energy phosphates, like adenosine triphosphate, in the storage and release of energy. During this work he discovered the enzyme polynucleotide phosphorylase, which plays an important role in the synthesis of ribonucleic acid (RNA). This enzyme provided the foundation for the subsequent synthesis of artificial RNA and the breaking of the human genetic code. Ochoa was awarded the Nobel Prize for Medicine in 1959 for his work on the biological synthesis of RNA.1905-09-24T00:00:00+0000| 24 Sep 1905 | | Severo Ochoa was born in Luarca, SpainOchoa | New York University |
Pirie was a virus physiologist and biochemist. He helped determine that the genetic component of viruses is RNA. Before this viruses were thought to be made up completely of proteins. During World War II he explored the possibility of extracting edible proteins from leaves, research that he carried on into the 1970s. His experiments were directed towards solving the food problem posed by the growing world population. He hoped to replace the inefficient method of feeding animals to secure protein for the diet.1907-07-01T00:00:00+0000| 1 Jul 1907 | | Norman Wingate (Bill) Pirie was born in Eastbourne, UKPirie | Rothamsted Experimental Station |
Stein was a biochemist who shared the 1972 Nobel Prize for contributing to understanding the composition and functioning of ribonuclease, an enzyme that catalyses the break down of RNA into smaller components. It was the first structure and sequence worked out for any enzyme. Stein carried out the work with his colleague Stanford Moore in 1963. The two scientists were aided by their invention of the first means for automated amino acid analysis. In addition to his work on ribonuclease, Stein showed how proteins that are comprised of the same amino acids can have very different characteristics and functions. 1911-06-25T00:00:00+0000| 25 Jun 1911 | | William H Stein was born in New York NY, USAStein | Rockefeller University |
Zamecnik pioneered the in vitro synthesis of proteins and helped determine the way cells generate proteins. Together with Mahlon Hoagland and Mary Stephenson he showed that protein synthesis was activated by adenosine 5'-triphosphate and that ribosomes were the site of protein assembly. He also subsequently helped to discover transfer RNA and is credited with laying the foundation for the development of antisense therapies, a type of gene therapy. 1912-11-22T00:00:00+0000| 22 Nov 1912 | | Paul Zamecnik was born in Cleveland, Ohio, USAZamecnik | Massachusetts General Hospital |

Holley was a biochemist who shared the 1968 Nobel Prize for Medicine for explaining how the genetic code controls the synthesis of proteins. This stemmed from his research on RNA which he began in the late 1940s. By 1960 and he and collaborators showed that amino acids were assembled into proteins by transfer RNAs (tRNAs). In 1965 he managed to determine the composition of a tRNA that incorporates the amino acid alanine into protein molecules. 1922-01-28T00:00:00+0000| 28 Jan 1922 | | Robert W Holley was born in Urbana IL, USAHolley | Cornell University |
A molecular biologist, Smith was a key pioneer in nucleic acid research. One of the few to realise the importance of nucleic acids before Watson and Crick uncovered the structure of DNA in 1953, Smith helped to elucidate the structure of ribonucleic acid molecules (RNA), the genetic material of many plant and animal viruses. This was helped by his development of paper chromatographic methods for analysing nucelosides and other units which make up DNA. He also helped to discover rare and unexpected modifications of DNA bases in bacterial genomes which are now understood to prevent attack from DNA viruses. 1924-12-08T00:00:00+0000| 8 Dec 1924 | | John D Smith was born in Southampton, UKJohn D Smith | California Institute of Technology, Laboratory of Molecular Biology |
A chemist and biophysicist, Klug won the 1982 Nobel Prize in Chemistry for the development of crystallographic electron microscopy. He used the technique to investigate nucleic acid-protein complexes and the structure of viruses. He developed an interest in viruses after meeting Rosalind Franklin in late 1953. Klug also discovered zinc-finger proteins, a class of proteins that bind specific DNA sequences. Scientists now use the modular nature of these proteins to design synthetic proteins for targeted therapies. Klug went to South Africa with his Jewish parents when he was two and then settled in England after completing his master's degree. Klug was the director of the Laboratory of Molecular Biology (1986-1996) and President of the Royal Society (1995-2000). 1926-08-11T00:00:00+0000| 11 Aug 1926 | | Aaron Klug was born in Zelvas, LithuaniaKlug | Laboratory of Molecular Biology |
Gilbert is a molecular biologist. He was involved in some of the early efforts to pioneer techniques for determining base sequences in nucleic acids, known known as DNA sequencing, for which he shared the Nobel Prize for Chemistry in 1980. He was the first scientist to propose the existence of intron and exons. In 1986 Gilbert became a proponent of the theory that the first forms of life evolved out of replicating RNA molecules. The same year he began campaigning to set up the Human Genome Project. He was also a co-founder and the first Chief Executive Officer of Biogen, a biotechnology company originally set up to commercialise genetic engineering.1932-03-21T00:00:00+0000| 21 Mar 1932 | | Walter Gilbert was born in Boston MA, USAGilbert | Harvard University, Biogen |
Altman is a molecular biologist who shared the 1989 Nobel Prize for Chemistry for discovering the catalytic properties of RNA. This emerged out of some work Altman carried out between 1978 and 1983 on a bacterial enzyme called RNAs-P.

It also opened up the possibility of using genetic engineering to develop new forms of therapy against viral infections. 1939-05-07T00:00:00+0000| 7 May 1939 | | Sidney Altman was born in Montreal, CanadaAltmann | Laboratory of Molecular Biology |
Yonath is a biochemist who won the Nobel Prize for Chemistry in 2009 for helping to map the structure of ribosomes, the molecule that helps translate RNA into protein. She started the research in the 1970s using x-ray crystallography. By 2001 she had worked out the complete high-resolution of structures of both ribosomal subunits and discovered a region important to the process of polypeptide polymerisation. In addition to this work Yonath had elucidated the modes of action of over 20 different antibiotics that target the ribsome, which has provided insights into the mechanisms of drug resistance and antibiotic sensitivity. 1939-06-22T00:00:00+0000| 22 Jun 1939 | | Ada E Yonath was born in Jerusalem, Palestine (now Israel)Yonath | Weizmann Institute |
Steitz is a biochemist and biophysicist who shared the 2009 Nobel Prize for Chemistry for elucidating the atomic structure and function of ribosomes, tiny particles made up of RNA and proteins involved in protein synthesis.

The work opened up a new pathway to the discovery and development of new classes of antibiotics. 1940-08-23T00:00:00+0000| 23 Aug 1940 | | Thomas A Steitz was born in Milwaukee, WI, USASteitz | Yale University |
Sharp is a geneticist and molecular biologist. He shared the 1993 Nobel Prize for Medicine for the discovery of RNA splicing. This was awarded on the back of some research he did in 1977 which showed that RNA can be divided up into introns and exons, after which the exons can be joined together. This process can happen in different ways. It provides the means for the gene to form a number of different proteins. Sharp also co-founded Biogen, set up in 1978, and helped found Alnylam Pharmaceuticals and Magen Biosciences.1944-06-06T00:00:00+0000| 6 Jun 1944 | | Phillip A Sharp was born in Falmouth, Kentucky, USASharp | Massachusetts Institute of Technology, Biogen, Alynylam Pharmaceuticals, Magen Biosciences |
Kornberg is a biochemist whose research is focused on working out the mechanism and regulation of transcription, which is the first step in the pathway of gene expression. In 2006 he won the Nobel Prize for working out the protein pathway that a cell's genetic information takes when transferred to a new cell. He showed how information is carried from the genes and converted to molecules called messenger ribonucleic acid (RNA). This he worked out by mapping out the process in yeast. Kornberg was the first to work out how transcription works at a molecular level in eukaryotes, a group of organisms, including humans, whose cells have a well-defined nucleus. 1947-04-24T00:00:00+0000| 24 Apr 1947 | | Roger D Kornberg was born in St. Louis, MO, USAKornberg | Stanford University |
Cech is a chemist who shared the 1989 Nobel Prize for Chemistry for the discovery of the catalytic properties of RNA. This was based on his investigation of splicing RNA in Tetrahymena thermophila, a unicellular organism, during the 1970s. He discovered that unprocessed RNA molecules could splice themselves and showed that RNA molecules are not restricted to being passive carriers of genetic information. 1947-12-08T00:00:00+0000| 8 Dec 1947 | | Thomas R Cech was born in Chicago IL, USACech | University of Colorado |

Fire is a biologist, pathologist and geneticist. In 1998 he and other colleagues working at Carnegie Institute reported in an article in Nature the discovery of tiny snippets of double-stranded RNA (dsRNA) that appeared to silence specific genes which destroyed messenger RNA, a molecule involved in the production of proteins. They hypothesised that this was caused by a catalytic process. In 2006 he shared the Nobel Prize for Medicine for helping to show the mechanism that controlled the flow of genetic information. 1959-04-27T00:00:00+0000| 27 Apr 1959 | | Andrew Z Fire was born in Stanford CA, USAFire | Carnegie Institute, Johns Hopkins, Stanford University |
Mello is a biologist who shared the 2006 Nobel Prize for Physiology or Medicine for the discovery of
RNA interference. This was based on work he carried out with colleagues to identify genes involved in regulating nematode development. He discovered that some nematode embryos injected with RNA to silence certain genes passed on the silencing effect to their offspring. On investigating further they found a double-stranded RNA was involved in the silencing phenomenon and that it is a defence mechanism against viral infection. The findings were published in 1998. 1960-10-19T00:00:00+0000| 19 Oct 1960 | | Craig C Mello was born in New Haven, CT, USAMello | University of Massachusetts |

A chemist and biophysicist, Klug won the 1982 Nobel Prize in Chemistry for the development of crystallographic electron microscopy. He used the technique to investigate nucleic acid-protein complexes and the structure of viruses. He developed an interest in viruses after meeting Rosalind Franklin in late 1953. Klug also discovered zinc-finger proteins, a class of proteins that bind specific DNA sequences. Scientists now use the modular nature of these proteins to design synthetic proteins for targeted therapies. Klug left Lithuania for South Africa with his Jewish parents when he was two. He went to England after completing his master's degree. Klug was the director of the Laboratory of Molecular Biology (1986-1996) and President of the Royal Society (1995-2000).2018-11-20T00:00:00+0000| 20 Nov 2018 | | Aaron Klug diedKlug | Birkbeck College, Laboratory of Molecular Biology |
