A gene bank is a popular term that is used to describe repositories for genes of living organisms. It is commonly used in the context of plant breeding as I described above, but it also applies to the freezing and the storage of animal sperm and embryos for use in animal husbandry or artificial insemination. An understanding of crop origins and variations is necessary in assembling genetic diversity in plant crops. In certain geographical areas there has existed a rich source of variability in crop plants but the encroachment of civilization has reduced the natural variability inherent in primitive plant forms and related species of crop plants. Agricultural process, as a result of new breeding programs, has reduced rather than increased crop variability as improved cultivars, or varieties, are planted in wider and wider areas and old cultivars, which may contain valuable genes, are lost.
Traditional breeding included different processes, such as sowing seeds from the resilient plants in order to produce a new generation. Farmers would grow plants with higher yield and resistance to pests, naturally alternating the genetic makeup of plants. Consequently, a vast majority of plants today bare resemblances of their lineage (Biotechnology Industry Organization 2010).

Before targeedt genome engineering emerged there was classical plant breeding and transgenic methods to modify crop plants, and ensure sustainable production. Researchers today have utilized methods like zinc finger nucleases (ZNF) and TAL effector nucleases (TALENs) to create these improved crop plants. Recently, a new method has caught the eye of many researchers; a method that simplifies the process and saves labor: CRISPR-Cas9 system. This method of genome engineering is particularly interesting not only for researchers but also for millions of Americans. In the last decade, there has been a surge of legislation concerning GMOs.
As Benson explains farmers today use organic farming, grass-fed animal raising, and biodiversity growing methods to sustain a long-term agricultural which creates nutrition rich food as well as nutrition rich soil(Benson, 2011). Nutrition rich food and Nutrition rich soil is well needed. Nutrition rich soil sustains agriculture conditions. Without it, crops don't have the proper conditions to grow, which decreases the crop and requires the need for international trade to make up what is lost.

Background: Some foundational understanding of the technology underlying TC production is necessary to adequately consider the issues at hand. To modify crops biologist use recombinant DNA (rDNA). This consists of extracting a gene producing a desirable trait from one organism and inserting it into the organism to be modified. Taking a gene for a desirable trait from a plant and amplifying its effect is also a method of genetic engineering using rDNA. The sources of genetic material to insert are almost boundless, crossing bounds between species and even forms of life.
With genetic engineering, all that must be done is find the correct DNA code you want to put in another plant. Once you locate the trait in a plant, you can put that trait in all of the other plants. The benefits of genetically modified organisms range from helping farmers efficiently meet the crop demand... ... middle of paper ... .... 2011. .

The Green Revolution began during the 1970s and 1980s, in an attempt to increase the nutrition in food crops and to make species of food crops more uniform and robust. Scientists developed strains of hybrid plants, such as wheat, rice, and maize that quantitatively produced more food that was of better quality. This research was led by Dr. Norman Borlaug in Mexico and others under the sponsorship of the Rockefeller Foundation during the 1960s. There were several techniques that the scientists used to help increase yield and appearance of crops. First, genetic engineering was used, such as cross breeding plants for desirable qualities.
Agricultural Revolution- Which One is the Best? Intro- The Agricultural Revolution is the period of time in which significant changes in agriculture has produced a significant effect on how food is produced. These revolutions range from first growing plants and raising animals to modify the genetic code of plants and animals to suit the needs of people. Although, certain Agricultural Revolutions may have much more of a significant impact, by how foods are mass produced and fed to people, especially in developing regions. For our opinion essay it would be with the third Agricultural Revolution, where international efforts are put in to produce much more food for the same amount of land area; through innovation, modification, cost, and the
This system could then be used to gather the spill for processing and prevent it from being wasted, but that is likely a technology for the future (“Environmental Biotechnology”). Prokaryotic organisms are essential to our lives now, directly or indirectly. They are used as genetic donors to create fruits and vegetables that increase yield and are the mechanism used to clean up various environmental hazards and make energy sources more efficient and readily available. Though these organisms are used in different ways, similar concerns apply to each, showing that there are still many obstacles to overcome for various types of engineers in the future.

Plant breeding is a common operation done by people in the agricultural field. It is the science of changing the traits of plants in order to produce desired characteristics. It is the process developing new plant varieties that goes by various names including ¨cultivar development, crop improvement, and seed improvement¨ (plantbreeding.org, n.d.). Breeding involves the creation of multi-generation genetically diverse populations on which human selection is practiced to create adapted plants with new combinations of specific desirable traits. The selection process is driven by ¨biological assessment in relevant target environments and knowledge of genes and genomes¨ (plantbreeding.org, n.d.).
