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 .
Herbert Wayne "Herb" Boyer (born July 10, 1936) is an American biotechnologist, researcher and entrepreneur in biotechnology. Along with Stanley N. Cohen and Paul Berg, he discovered recombinant DNA, a method to coax bacteria into producing foreign proteins, which aided in jump-starting the field of genetic engineering.
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]).
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.
Stanley Norman Cohen (born February 17, 1935) is an American geneticist [2] and the Kwoh-Ting Li Professor in the Stanford University School of Medicine. [3] Stanley Cohen and Herbert Boyer were the first scientists to transplant genes from one living organism to another, a fundamental discovery for genetical engineering.
Berg was the first scientist to create a molecule containing DNA from two different species by inserting DNA from another species into a molecule. This gene-splicing technique was a fundamental step in the development of modern genetic engineering. After developing the technique, Berg used it for his studies of viral chromosomes. [13]
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 .
