The history of genetics can be represented on a timeline of events from the earliest work in the 1850s, to the DNA era starting in the 1940s, and the genomics era beginning in the 1970s. Early timeline
In 1960, Jacob and collaborators discovered the operon which consists of a sequence of genes whose expression is coordinated by operator DNA. [30] In the period 1961 – 1967, through work in several different labs, the nature of the genetic code was determined (e.g. [31]).
2010: The Neanderthal Genome Project presented preliminary genetic evidence that interbreeding likely occurred and that a small but significant portion of Neanderthal admixture is present in modern non-African populations. [134] 2012: Higgs boson is discovered at CERN (confirmed to 99.999% certainty) 2012: Photonic molecules are discovered at MIT
In 1952, Alfred Hershey and Martha Chase confirmed that the genetic material of the bacteriophage, the virus which infects bacteria, is made up of DNA [4] (see Hershey–Chase experiment). In 1953, James Watson and Francis Crick discovered the double helical structure of the DNA molecule based on the discoveries made by Rosalind Franklin. [5]
1972 – The DNA composition of chimpanzees and gorillas is discovered to be 99% similar to that of humans. 1973 – Stanley Norman Cohen and Herbert Boyer perform the first successful recombinant DNA experiment, using bacterial genes. [6] 1974 – Scientists invent the first biocement for industrial applications.
Scientists said on Wednesday they identified through ancient DNA 13 Homo sapiens skeletal remains in Ilsenhöhle cave, situated below a medieval hilltop castle in the German town of Ranis.
Proponents of genetic engineering cite its ability to cure and prevent life-threatening diseases. Genetic engineering began in the 1970s when scientists began to clone and alter genes. From this, scientists were able to create life-saving health interventions such as human insulin, the first-ever genetically engineered drug. [133]
A map may prove that Marco Polo discovered America more than two centuries before Christopher Columbus. A sheepskin map, believed to be a copy of the 13th century Italian explorer's, may indicate ...
