Will GMOs revolutionize the food and health industries or will they cause damage and downfall? Moreover, is it even ethical to tamper with nature and release science fiction into the food supply? GMOs and the History Behind Them Genetic modification has been present in agriculture since the Egyptians and the Sumerians first developed it over four thousand years ago. While modification was first used at a very basic level, today it involves implantation of DNA from one organism to another. The basis for genetic modification occurred in the 1970's when the technology to isolate individual genes and alter and copy them in cells was developed.
We possibly overlook the microorganisms when thinking of LMO since plants and animals probably will first come to our mind. With the development of recombinant DNA technology, metabolic potentials of microorganisms are being explored. Nowadays, genetically modified microorganisms (GMMs) have vast applications in human and animal health, bioremediation, and in industries such as food and textiles. The first GMM, specifically E. coli, was made in the 1970s (Teisha, 2013). A few years later, GMMs which produced essential human proteins were churned out by researchers (Teisha, 2013).
It wasn’t until 1972 when Paul Berg utilised enzymes and DNA to create the first recombinant DNA molecule. The combination of monkey virus SV40 and lamba virus was used to create the first recombinant DNA. A year later in 1973 Rudolf Jaenisch created a transgenic mouse. Jaenisch was able to do this by introducing foreign DNA into its embryo. This process created the first transgenic animal.

A genetically modified organism is a plant, animal, or microorganism whose genetic material has been altered using genetic engineering. Genetic engineering is the process of adding new DNA to an organism, in order to give it new traits it does not naturally grow. DNA from one organism is combined with another organism’s DNA to make one molecule, which then forms a new set of genes. It is then transferred into the organism so it can now have modified genes. Bacteria were the first organisms to be genetically modified in 1973.
Genetic engineering includes a range of techniques used by scientists to control or modify genes, switch them off or move them between two unrelated species. Using genetic engineering, scientists aim to introduce, enhance or delete particular characteristics of a living thing, depending on whether they are considered desirable or undesirable.

Genetic Engineering in Agriculture Introduction Genetic Engineering is the technical manipulation of an object from the natural world in a way in which it would provide a benefit to humans. Genetic engineering is also known as recombinant DNA technology which means changing the genes in a living organism to produce a Genetically Modified Organism (GMO) with a new genotype. Various kinds of genetic modification are possible such as inserting a foreign gene from one species into another, forming a transgenic organism; altering an existing gene so that its product is changed; or changing gene expression so that it is translated more often or not at all . Genetic engineering is also sometimes called bioengineering, genetic manipulation, gene technology and biotechnology i.e. the industrial use of biological processes.
In 1944, Avery and his colleague identified DNA as the molecular information carrier, providing definitive proof that DNA is the hereditary material (Avery et al., 1944). They confirmed that chemically isolated DNA from the cell possessed the same inheritability as the heat-treated extract. In 1931, Barbara McClintock and Harriet Creighton demonstrated direct physical recombination by examining maize chromosomes microscopically (Coe, E., & Kass, L. B., 2005). McClintock and Creighton’s maize breeding experiments provided the first detailed descriptions of transposable elements. In 1973-1974, Stanley Cohen, Annie Chang and Herbert Boyer of the University of California, San Francisco created the first genetically modified DNA organism (Hughes, 2001).
The founding of genetically modified organisms was extended through the course of many years. It began in 1865 when Gregor Mendel observed hereditary characteristics in pea plants. Nearly forty years later, Andrei Nikolaevitch Belozersky was the first person to isolate DNA, or “factors”, as Mendel defined it, in its pure state (Life Sciences Foundation, Purification of DNA). This revelation sparked the start to DNA innovations. After the discovery of DNA’s structure by Watson and Crick, scientists continued to crack the code, and DNA modification became possible when Professor Herbert Boyer created recombinant DNA (Chemical Heritage Foundation, Paul Berg, Herbert W. Boyer, and Stanley N. Cohen).
GM foods cause many assorted viewpoints consisting of positive and negative effects based off of its recent history. The history and the different ways of genetically modifying the GM foods started very recently, extending to only the past 50 years. The genetics all began when a monk discovered that all creatures are made up of genes. GM started with two different ways of genetically modifying organisms. Cisgenesis, the process of scientists taking genes from an animal or plant and altering the genes of an organism in the same species, was the first way.
