"The wide concept of ""biotech"" or ""biotechnology"" encompasses a wide range of procedures for" Genetically modified crops. Genetically modified crops (GM crops, or biotech crops) are plants used in agriculture, the DNA of which has been modified using genetic engineering techniques. In most cases the aim is to introduce a new trait to the plant which does not occur naturally in the species.

Genetic Engineering Gene targeting is a different technique that uses homologous recombination to change an endogenous gene, and can be used to delete a gene, remove exons, add a gene, or introduce point mutations. An organism that is generated through genetic engineering is considered to be a genetically modified organism (GMO).The first GMOs were bacteria generated in 1973 and GM mice in 1974. Insulin-producing bacteria were commercialized in 1982 and genetically modified food has been sold since 1994.enetic engineering alters the genetic make-up of an organism using techniques that remove heritable material or that introduce DNA prepared outside the organism either directly into the host or into a cell that is then fused or hybridized with the host.

Top 7 Genetically Modified Crops 1. Corn: Corn is the No. 1 crop grown in the U.S. and nearly all of it -- 88 percent -- is genetically modified. In addition to being added to innumerable processed foods, genetically modified corn is a staple of animal feed.2. Soy: 93 percent of soy is genetically modified.Soy is a staple of processed foods under various names including hydrogenated oils, lecithin, emulsifiers, tocopherol (a vitamin E supplement) and proteins.he top three GMO crops grown in the U.S. are soy, corn and cotton, according to the U.S. Department of Agriculture (USDA). During the past 12 years, the percentage of acreage planted with GMO crops soared to over 80 percent for each of the top three.

Transgenic Organisms Modern genetic technology can be used to modify the genomes of living organisms. This process is also known as “genetic engineering.” Genes of one species can be modified, or genes can be transplanted from one species to another. Genetic engineering is made possible by recombinant DNA technology. Organisms that have altered genomes are known as transgenic. Most transgenic organisms are generated in the laboratory for research purposes. For example, “knock-out” mice are transgenic mice that have a particular gene of interest disabled.

What is Genetic Engineering? Genetic engineering, also known as biotechnology, is the process of manually adding new DNA to an organism. The goal of genetic engineering is to add one or more new traits that are not already found in that organism.ecombinant DNA. Recombinant DNA technology is the modification of the sequences of the DNA bases in order to change the observable form and function of an organism. Recombinant DNA is a form of artificial DNA which is created by combining two or more sequences of DNA that would not normally occur together.

- A bacteria with the name Agrobacterium Tumefasciens has the ability to induce a kind of benign tumor growth in the plant it infects. This it achieves by inserting some genes into the DNA of the plant. In genetic engineering, the gene that is to be inserted is hooked on to the bacterial DNA.Then the recipient cells are exposed to the bacterium, so that they become infected by it.pecial techniques are used, that are of no imporance here. 2. A gene is much too small to be inserted with some kind of microsurgery. Therefore some carrier (vector) is required which takes the gene into the recipient cell and somemhow gets it inserted into the DNA of the recipient.

- Gene targeting is a genetic technique that uses homologous recombination to change an endogenous gene. The method can be used to delete a gene, remove exons, add a gene, and introduce point mutations. Gene targeting can be permanent or conditional. Conditions can be a specific time during development / life of the organism or limitation to a specific tissue, for example. Gene targeting requires the creation of a specific vector for each gene of interest. However, it can be used for any gene, reg

- When farmers start growing genetically modified crops, they stop growing the old varieties. These old varieties are important sources of diverse genes that give plants other desirable characteristics. For example, a new pest or disease could come along and destroy the genetically modified rice.If one of the old rice varieties has a gene that makes it resistant, it could be cross-bred to make the saltwater rice resistant as well. If we lose the old varieties, we also lose their useful genes. You are a tomato farmer whose crops are threatened by a persistent species of beetle. 2  Each year, you spend large sums of money for pesticides to protect your crops. 3  A biotechnology company introduces a new strain of tomato plant that produces a natural pesticide, making it resistant to the beetle.
