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 |
A hybridization probe used in molecular diagnosis is commonly tagged with a radioactive isotope to allow for its visualization. A common such radioactive isotope that can be used is:
| 1. | 60Co | 2. | 32P |
| 3. | 15N | 4. | 131I |

Production of transgenic plants is easier than the production of transgenic animals mainly because:
| 1. | Plant cells can grow in cell culture. |
| 2. | Plant cells have a lower number of potentially lethal genes. |
| 3. | Plant cells are totipotent. |
| 4. | Plants do have cancers. |
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 |
Protoplast fusion can be achieved with the use of:
| 1. | Colchicine | 2. | Polyethylene Glycol |
| 3. | Polyacryl amide | 4. | Ethidium bromide |

Somatic embryo regeneration in micropropagation is induced by high concentrations of:
| 1. | Cytokinins | 2. | Gibberellins |
| 3. | Auxins | 4. | Zinc |
Plantlets regenerated during micropropagation are subjected to hardening where they are grown in the conditions of:
1. sufficient light and high humidity
2. sufficient light and low humidity
3. decreased light and high humidity
4. decreased light and low humidity
| 1. | Classical hybridization | 2. | Mutation breeding |
| 3. | Plant tissue culture | 4. | Genetic engineering |
| I: | Spores and crystalline insecticidal proteins produced by B. thuringiensis are now used as insecticides in organic farming. |
| II: | Because of their specificity, these pesticides are regarded as environmentally friendly, with little or no effect on humans, wildlife, pollinators, and most other beneficial insects. |
1. Both I and II are correct and II explains I
2. Both I and II are correct but II does not explain I
3. I is correct but II is incorrect
4. I is incorrect but II is correct
