    In 1960, Jacob and collaborators discovered the operon which consists of a sequence of genes whose expression is coordinated by operator DNA. [27] In the period 1961 – 1967, through work in several different labs, the nature of the genetic code was determined (e.g. [28]).

    1969: Molecular hybridization of radioactive DNA to the DNA of cytological preparation by Pardue, M. L. and Gall, J. G. 1970: Restriction enzymes were discovered in studies of a bacterium, Haemophilus influenzae, by Hamilton O. Smith and Daniel Nathans, enabling scientists to cut and paste DNA. [44]

    The combination, in the 1930s and 1940s, of Mendelian genetics with Darwin's theory of natural selection resulted in the modern synthesis of evolutionary biology. [50] [51] In the Soviet Union and China, Mendelian genetics was rejected in favor of Lamarckism, leading to imprisonment and even execution of Mendelian geneticists (see Lysenkoism).

    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

    Deoxyribozymes, also called DNAzymes or catalytic DNA, were first discovered in 1994. [170] They are mostly single stranded DNA sequences isolated from a large pool of random DNA sequences through a combinatorial approach called in vitro selection or systematic evolution of ligands by exponential enrichment (SELEX).

    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]
