Plants genetically engineered to make them resistant to glyphosate was an important achievement because:
| 1. | glyphosate promotes frost damage |
| 2. | glyphosate encourages the production of fruit that is lower in protein |
| 3. | glyphosate is the active ingredient in herbicides |
| 4. | glyphosate prevents the transfer of genes into the plants |

You want to transform the cells of sugarcane plants with the objective of introducing a disease-resistant gene in sugarcane plants. The best method to achieve this goal would be:
| 1. | The use of a gene gun |
| 2. | Microinjection |
| 3. | Agrobacterium tumefaciens mediation |
| 4. | Delivery of DNA by liposomes |
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 |
Golden rice was created by:
| 1. | hybridization of institutional rice varieties with wild varieties |
| 2. | mutation breeding using gamma rays |
| 3. | by transforming rice with two beta-carotene biosynthesis genes, one from a eukaryote and another from a prokaryote |
| 4. | by transforming rice with two beta-carotene biosynthesis genes from two different prokaryotes |
