The Transgenic Tomato Essay examples -- Science Genetics Papers

The Transgenic TomatoThe necessity for Genetic Engineering of Crops For most Americans, fresh vegetables come from the supermarket. One however has to walk down an aisle loaded with gleaming red tomatoes, productive melons, fresh potatoes, and a plethora of other vegetables and fruits and gather whatever captures ones romance or appetite. A person living in a Westernized enculturation lots takes for granted the hard work, resource usage, and waste that occurs to bring diet to him. Tomatoes, for example, currently follow a long and difficult route to the supermarket. To initiate with, field workers must pick the tomatoes by hand while they argon still green. The unripe tomatoes argon then trucked to facilities where they are gassed with ethylene to unnaturally induce ripening (Engel 108). Treating green tomatoes with gas to make the red dissimulation appear before the tomato ripens allows them to be shipped with less bruising and spoil because they are still hard, but this pr actice detracts from their flavor and makes them taste, as roughly like to say, like cardboard After the tomatoes are gassed, the red (but tough) tomatoes are distributed to the supermarkets. The cardboard tomato problem illustrates a larger problem in agriculture - crop spoilage associated with the predations of insects and fungi and with shipping. We saw that picking fruits such(prenominal) as tomatoes while they are green and chemically ripening them is a solution to some of the spoilage problem in crops, while break offment other chemicals can prevent some damage by pests. However, these chemicals often create environmental hazards in areas where they are used, and pests can often develop resistance to chemicals used to destroy them, making the release of even more(prenominal) pesticides and fungicides int... ...ill form a string, and the tRNA molecules will be released into the cell. When this string of aminic acids is completed, it is called a protein. Some proteins pro vide structure in living things (such as the protein in muscle tissue), while others can promote certain chemical reactions in cells (such as the breakdown of pectin in tomato cell walls).The supra information was taken from Biology, Neil Campbell, et. al., New York Addison Wesley, 1999, p.316.Works CitedCampbell, Neil et. al.
