Which of the following is not an application of PCR (Polymerase Chain Reaction)?
1. Purification of isolated protein
2. Detection of gene mutation
3. Molecular diagnosis
4. Gene amplification
When gene targeting involving gene amplification is attempted in an individual's tissue to treat disease, it is known as:
| 1. | Molecular diagnosis | 2. | Safety testing |
| 3. | Biopiracy | 4. | Gene therapy |
Nowadays, it is possible to detect the mutated gene causing cancer by allowing the radioactive probe to hybridise its complementary DNA in clone of cells, followed by its detection using autoradiography because:
| 1. | mutated gene does not appear on a photographic film as the probe has no complementarity with it. |
| 2. | mutated gene does not appear on a photographic film as the probe has complementarity with it. |
| 3. | mutated gene partially appears on a photographic film. |
| 4. | mutated gene completely and clearly appears on a photographic film. |
With regard to insulin, choose the correct options:
| (a) | C-peptide is not present in mature insulin. |
| (b) | The insulin produced by rDNA technology has C-peptide. |
| (c) | The pro-insulin has C-peptide. |
| (d) | A-peptide and B-peptide of insulin are interconnected by disulphide bridges. |
| 1. | (a), (c) and (d) only | 2. | (a) and (d) Only |
| 3. | (b) and (d) only | 4. | (b) and (c) only |
| 1. | ELISA Technique | 2. | Hybridization Technique |
| 3. | Western Blotting Technique |
4. | Southern Blotting Technique |
The Adenosine deaminase deficiency results into:
| 1. | Digestive disorder | 2. | Addison's disease |
