...they began the study of the development of eye pigment in Drosophila which later led to the work on the biochemistry of the genetics of the fungus Neurospora for which Beadle and Edward Lawrie Tatum were together awarded the 1958 Nobel Prize for Physiology or Medicine.

 

A critical influence in Crick's career was his friendship, beginning in 1951, with J. D. Watson, then a young man of 23, leading in 1953 to the proposal of the double-helical structure for DNA and the replication scheme.

Discoveries concerning the replication mechanism and the genetic structure of viruses..

In the middle seventies, Allan Maxam and I developed the rapid chemical DNA sequencing. At this time, I also became interested in and developed some of the recombinant DNA techniques

Nobel prize in 1969 for their discoveries concerning the replication mechanism and the genetic structure of viruses

The work of François Jacob has dealt mainly with the genetic mechanisms existing in bacteria and bacteriophages, and with the biochemical effects of mutations.

There were many other investigations on growth factors for flagellates and ciliates with regard to growth factors, loss of function, and physiological development until the time when Lwoff began working on the problem of lysogenic bacteria.

The people, texts, and events briefly described in the MendelWeb Timeline, and the links to sources of information that elaborate and explain them, are not meant to be exhaustive in any sense. The timeline is merely designed to reflect, and motivate studies of, some of the things that were happening while Mendel was alive.

To George Teissier he owes a preference for quantitative descriptions; André Lwoff initiated him into the potentials of microbiology; to Boris Ephrussi he owes the discovery of physiological genetics, and to Louis Rapkine the concept that only chemical and molecular descriptions could provide a complete interpretation of the function of living organisms.

The subjects of the papers he published reflect his great scientific versatility: about 350 publications in the fields of experimental determination of the structure of crystals by the diffraction of X-rays and the interpretation of these structures in terms of the radii and other properties of atoms;

Rosalind Franklin always liked facts. She was logical and precise, and impatient with things that were otherwise. She decided to become a scientist when she was 15. She passed the examination for admission to Cambridge University in 1938, and it sparked a family crisis....

I succeeded in developing new methods for amino acid sequencing and used them to deduce the complete sequence of insulin, for which I was awarded the Nobel Prize for Chemistry in 1958...

...when he and Beadle decided to give up their work on Drosophila and to work instead with the fungus Neurospora crassa, it was Tatum who discovered that biotin was necessary for the successful cultivation of this fungus on simple inorganic media and thus provided these two workers with the genetic material that they needed for the work which gained them, together with Joshua Lederberg, the Nobel Prize.

He soon met Crick and discovered their common interest in solving the DNA structure. They thought it should be possible to correctly guess its structure, ...

The discovery of the well-defined patterns led to the deriving of the molecular structure of DNA. Further X-ray studies established the correctness of the Watson-Crick proposal for DNA structure.
