1992: American and British scientists unveiled a technique for testing embryos in-vitro (Amniocentesis) for genetic abnormalities such as Cystic fibrosis and Hemophilia. 1993: Phillip Allen Sharp and Richard Roberts awarded the Nobel Prize for the discovery that genes in DNA are made up of introns and exons.
A focus on new model organisms such as viruses and bacteria, along with the discovery of the double helical structure of DNA in 1953, marked the transition to the era of molecular genetics. In the following years, chemists developed techniques for sequencing both nucleic acids and proteins, while many others worked out the relationship between ...
1961 – Francis Crick, Sydney Brenner, Leslie Barnett and R.J. Watts-Tobin prove the triplet nature of the genetic code. 1961 – Marshall W. Nirenberg and J. Heinrich Matthaei deciphered the first codon of the genetic code. 1964 – Marshall W. Nirenberg and Philip Leder deciphered the rest of the genetic code.
The timeline begins at the Bronze Age, as it is difficult to give even estimates for the timing of events prior to this, such as of the discovery of counting, natural numbers and arithmetic. To avoid overlap with timeline of historic inventions , the timeline does not list examples of documentation for manufactured substances and devices unless ...
The Genetics Society of America annually awards the Thomas Hunt Morgan Medal, named in his honor, to one of its members who has made a significant contribution to the science of genetics. Thomas Hunt Morgan's discovery was illustrated on a 1989 stamp issued in Sweden, showing the discoveries of eight Nobel Prize-winning geneticists. [citation ...
Genetic engineering is the science of manipulating genetic material of an organism. The concept of genetic engineering was first proposed by Nikolay Timofeev-Ressovsky in 1934. [ 1 ] The first artificial genetic modification accomplished using biotechnology was transgenesis, the process of transferring genes from one organism to another, first ...

Merton believed that it is multiple discoveries, rather than unique ones, that represent the common pattern in science. [4] Merton contrasted a "multiple" with a "singleton"—a discovery that has been made uniquely by a single scientist or group of scientists working together. [5] The distinction may blur as science becomes increasingly ...
