Genetic engineering of nitrogen fixation is made difficult by the fact that it :
1. is a complex process involving many enzymes
2. is a process that is partly anaerobic
3. involves about 15 genes (the Nif Genes)
4. All of these
The genetically engineered vaccine for the prevention of hepatitis B is made with the help of the microbe :

3. | Saccharomyces | 4. | Pseudomonas |
Which of the following genetic disease would be amenable to genetic engineering?

Prior to the production of recombinant human insulin, diabetic patients could use insulin isolated from cattle. Which of the listed items would not be a drawback to this procedure?
1. | Insulin from cattle is slightly different from human insulin, potentially leading to allergic reactions. |
2. | Members of some religions consider cattle sacred and thus are unable to use insulin isolated from cattle. |
3. | Infectious diseases may be transferred in the isolated insulin. |
4. | Despite the relatively stable supply of cattle pancreases from slaughterhouses, insulin isolated from cattle is still relatively expensive and is in, somewhat, limited supply. |

Bacteria that are unable to synthesize chemicals that allow the formation of ice crystals have been engineered. Commercial fruit farmers can spray this bacterial strain on their fruit plants, with the idea that they will compete with unmodified bacteria and reduce frost damage. This is an example of:
1. | Bioremediation | 2. | Biological control |
3. | Biodegradation | 4. | Bioeradication |
In gene knockout technology:
1. | A gene is inserted by nonhomologous recombination. |
2. | A mutant gene is replaced by a functional copy. |
3. | A functional gene is replaced by a mutant copy. |
4. | A functional gene is inserted in addition to the mutant copy. |
Which of these uses of transgenic technology is not directly relevant to agricultural applications?
1. | Production of a pharmaceutical protein in goat's milk. |
2. | Production of salmon that grow all year round instead of just in warm weather. |
3. | Production of soybean plants that are resistant to herbicides. |
4. | Production of "super mice" that carry the human growth hormone gene. |
