To produce human recombinant insulin, Eli Lily:
| 1. | prepared two DNA sequences corresponding to A and B chains of human insulin and introduced them in plasmids of E. coli to produce insulin chains. |
| 2. | prepared two DNA sequences corresponding to A and C chains of human insulin and introduced them in plasmids of Yeast to produce insulin chains. |
| 3. | used reverse transcription of the hnRNA transcript of the insulin gene to make complementary DNA. |
| 4. | used fragments created by restriction enzyme digestion to isolate and used the gene for insulin from pancreatic cells. |

| Assertion (A): | Transgenic animals can be specifically designed to allow the study of how genes are regulated, and how they affect the normal functions of the body and its development, e.g., study of complex factors involved in growth such as insulin-like growth factor. |
| Reason (R): | By introducing genes from other species that alter the formation of this factor and studying the biological effects that result, information is obtained about the biological role of the factor in the body. |
| 1. | Both (A) and (R) are True and the (R) is the correct explanation of the (A) |
| 2. | Both (A) and (R) are True but the (R) is not the correct explanation of the (A) |
