Various genetic discoveries have been essential in the development of genetic engineering. Genetic inheritance was first discovered by Gregor Mendel in 1865 following experiments crossing peas. Although largely ignored for 34 years he provided the first evidence of hereditary segregation and independent assortment. [ 16 ]
Genetic engineering, also called genetic modification or genetic manipulation, is the modification and manipulation of an organism's genes using technology. It is a set of technologies used to change the genetic makeup of cells, including the transfer of genes within and across species boundaries to produce improved or novel organisms .
Gregor Johann Mendel OSA (/ ˈ m ɛ n d əl /; Czech: Řehoř Jan Mendel; [2] 20 July 1822 [3] – 6 January 1884) was an Austrian [4] [5] biologist, meteorologist, [6] mathematician, Augustinian friar and abbot of St. Thomas' Abbey in Brno (Brünn), Margraviate of Moravia.
1989: Thomas Cech discovered that RNA can catalyze chemical reactions, [60] making for one of the most important breakthroughs in molecular genetics, because it elucidates the true function of poorly understood segments of DNA. 1989: The human gene that encodes the CFTR protein was sequenced by Francis Collins and Lap-Chee Tsui.
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]).
David P. Bartel (B.A. 1982), US geneticist, discovered many microRNAs regulating gene expression; William Bateson (1861–1926), British geneticist who coined the term "genetics" Erwin Baur (1875–1933), German geneticist, botanist, discovered inheritance of plasmids; George Beadle (1903–1989), US Neurospora geneticist and Nobel Prize-winner
1838 – Protein discovered, named and recorded by Gerardus Johannes Mulder and Jöns Jacob Berzelius. 1862 – Louis Pasteur discovers the bacterial origin of fermentation. 1863 – Gregor Mendel discovers the laws of inheritance. 1864 – Antonin Prandtl invents first centrifuge to separate cream from milk.
Genetic inheritance was first discovered by Gregor Mendel in 1865, following experiments crossing peas. [3] In 1928 Frederick Griffith proved the existence of a "transforming principle" involved in inheritance, which was identified as DNA in 1944 by Oswald Avery, Colin MacLeod, and Maclyn McCarty .
