I: | Gene therapy involves the introduction of a functional gene into the cells of an individual to treat genetic disorders. |
II: | RNA interference (RNAi) is a technique used to silence specific genes by degrading their structural genes located on template DNA. |
III: | Transgenic organisms are those that have been genetically modified to express desirable traits. |
1. | Decrease their susceptibility to diseases for research purposes. |
2. | Produce substances that are useful for medical applications. |
3. | Decrease their growth rate to study developmental processes. |
4. | Reproduce through asexual means, increasing population uniformity. |
Assertion (A): | The milk of Rosie, the first transgenic cow, was nutritionally a more balanced product for human babies than natural cow milk. |
Reason (R): | The milk of Rosie, the first transgenic cow, contained alpha-1-antitrypsin used to treat emphysema. |
