Q. No.“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. |
