Genetically modifying seeds to produce herbicide-resistant plants that increase crop yields has revolutionized modern agriculture. However, genetically modified organisms (GMOs) have come under fire in recent years, with consumer groups calling for mandatory GMO labeling on all food packages that contain GMO ingredients. GMO labeling laws have been in force in the European Union and other countries for several years, but the threat to the U.S. food industry is only now surfacing. Although bills requiring GMO labeling have been introduced in many state legislatures, Vermont is the only state where such a law has so far withstood the first round of legal battles from the industry. Leading chemical companies, including Monsanto, BASF, and DuPont, are the world’s largest suppliers of seeds that grow the food that feeds the world. To counter the GMO labeling threat, they now are turning to mutagenesis as an alternative technique to create herbicide-resistant crops. Mutagenesis mimics the…

Genetically modified foods are products produced from organisms that have had genetic
modifications introduced into their DNA. The Hawaiian Rainbow papaya, Flavr Savr tomatoes
and Roundup Ready soyabeans are products of this technology. Discuss the advantages of these
three genetically modified crops.

Make a tabulation of its use's positive and negative consequences as well as ethical issues. Landmines in many countries worldwide remind us of dreadful wars in the past and these too still prey on innocent lives who accidentally step on them. There is an interesting research however on a genetically modified plant species, Arabidopsis thaliana which detects the presence of land mines through changing colors. In a particular study, a gene that turns-on the production of the red pigment, anthocyanin in the presence of nitrogen dioxide has been inserted in the genome of thale cress (A. thaliana). As the modified plant already renders a sensitivity to the presence of nitrogen dioxide gas, in areas where unexploded landmines exist, the leaves of these plants turn from green to red, signaling the presence of nitrogen oxide gases released by these buried bombs (Nelson, 2004).

Reactive Oxygens species that damage DNA are removed by catalase C. On average, humans are exposed to more naturally occurring plant pesticides compared to man made pesticides. D. Cancer cells upregulate concentration of Glutathione S-Transferase (GST) to remove electrophilic compounds E. High levels of melanin are correlated with increased risk of skin cancerarrow_forwardAnswer the following correctly. Designer Genes Work (This is all about Applications of Recombinant DNA). Illustrate Designer genes using this information: The Arctic apple is a fruit engineered to resist browning after being cut. Currently they are only available in the US – in golden, fuji and gala varieties – where they have been given Food and Drug Administration approval. If approved in Europe, they would have to be labelled as genetically modified. The manufacturers claim the main benefit is to help cut down on food waste. And based on the following: a. Identify a special trait. b. Identify a source organism. c. Identify a target organism d. Identify the modified/added trait.

What is random mutagenesis?arrow_forwardWhich letter is correct A. Genetic engineering is preferred because a desired gene to crops may not exist in their species, so conventional agriculture could not be applied. B. Conventional agriculture is preferred because they're natural, and don't have interference in their genome, so they're healthier. C. Genetic engineering is preferred because through it, we can create new species of plants resistant to pests. D. Conventional agriculture is preferred because they produce more crop compared to genetic modifications.arrow_forwardBacteria are the most common GMOs because their simple structure permits easy manipulation of their DNA. This manipulation or genetic modification can be completed by series of steps and processes.
