“Flavr Savr” is the name of the first genetically modified:
1. food approved for human use
2. salmon fish
3. herbicide-resistant plant
4. bacterium capable of remediation in oil spills
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 study of all the proteins encoded by the genome of an organism is called :
1. | Proteome | 2. | Proteomics |
3. | Translation studies | 4. | Genomics |
Match each item in Column I with one item in Column II and chose your answer from the codes given below.
Column I (transgenic) |
Column II (application) |
I. Flavr savr II. Golden rice III. Sheep IV. Pig |
1. Increased shelf life 2. Vitamin A enriched 3. Xenotransplantation 4. Therapeutic human proteins |
Codes:
I | II | III | IV | |
1. | 1 | 2 | 3 | 4 |
2. | 2 | 1 | 4 | 3 |
3. | 2 | 1 | 3 | 4 |
4. | 1 | 2 | 4 | 3 |
The first transgenic sheep to produce alpha 1 antitrypsin was :
1. | Rosie | 2. | Dolly |
3. | Tracy | 4. | Andy |
Consider the two statements:
I: | Retroviruses are useful as vectors in gene therapy. |
II: | They can produce useful gene products in significantly greater quantities than a single human cell can. |
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. Only I is correct.
4. Both I and II are incorrect.
The sheep “Dolly” was cloned by using somatic cells from the donor’s:
1. | udder | 2. | skin |
3. | tongue | 4. | ear lobe |
Clearing up oil spills has been possible due to the use of genetically engineered:
1. | E.coli | 2. | Agrobacterium |
3. | Saccharomyces | 4. | Pseudomonas |
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. |
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. |
