Chapter 23, Problem 2WIO
Summary Introduction
To explain:
How transgenic technology might be used to endow plants with the ability to fix nitrogen without the help of bacteria and determine in what ways this new technology may change agriculture.
Concept introduction:
Transgenic organisms are those organisms that have altered or modified genomes. The genes from one species can be transferred into the genes of another by using recombinant DNA technology. These techniques are used in agriculture to increase the crop yield.

When might genetically modified (GMO) plants be of benefit?
An important goal of molecular botanists is to insert the genes for nitrogen fixation into crop plants such as corn or wheat. Why would the insertion of such genes be useful? What changes in farming practices would this technique allow?
Certain genetically modified tomatoes were designed to suppress (reduce the effectiveness) the enzyme polygalactias which delays ripening.
How does this gene modification affect the consumer and the diet of individuals in developing countries?
options:
Delaying the ripening process means that the tomatoes have a longer shelf life. The tomatoes survive delivery to the consumer and provide nutritional value to more people.
Delaying the ripening process means that the tomatoes can stay on the vine longer to receive nutrients. Once picked, these tomatoes will ripen rapidly to provide a full taste to the consumer.
Delaying the ripening process means that the tomatoes are more likely to freeze on the vine before becoming ripe. This freezing process locks in the minerals and beneficial nutrients so that the tomato can be transported without losing its nutritional benefit.
Delaying the ripening process means that the tomatoes are more likely to have a shorter shelf…

- What is the role of Agrobacterium tumefaciens in the production of transgenic plants? a. Genes from A. fume fociens are inserted into plant DNA to give the plant different traits. b. Transgenic plants have been given resistance to the pest A. tumefacaens. c. A. wmefaciens is used as a vector to move genes into plant cells. d. Plant genes are incorporated into the genome of Agrobacterium tumefaciens.arrow_forwardIn what way has biotechnology had an impact on agriculture in the United States?arrow_forwardGenetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops. Why do you think there is push back or opposition against the use of GM food crops but not in the use of products such as insulin, which is also created using GMOs?arrow_forward
- These weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them. For a few years, the farmer relies on manually removing the weeds, but that is labor intensive and limits how much crop he can grow. The farmer decided to change his crop to genetically modified soybeans that are herbicide resistant. This allows the farmer to use chemicals to remove the weeds. With this GM soybean, the chemical kills the weeds but does not harm the crop. For many years this works, and allows the farmer to expand his farm and grow more soybeans. But then, one of the farmer's fields has a large weed plant remaining after the field has been sprayed with herbicide. Which of the following is likely to happen if that weed stays in place? The weed will survive long enough to reproduce. In time, the herbicide will no longer be effective on that field. The trait will spread to nearby weeds.arrow_forwardThese weeds are growing in a farmer's field. The weeds compete with the soybean plants the farmer grows, so he needs to get rid of them.
