How bacteria were taught to make human insulin, how a faulty gene can be repaired in a patient, and how a tiny amount of a germ can be found early. Then the animals that carry a foreign gene, and what they are used for. It covers the unit of the Indian syllabus (NCERT, NEET) and the matching topic of A-Level, IB and AP.

Insulin was once taken from cattle and pigs, and it sometimes caused an allergy. Bacteria now make human insulin, in two chains that are joined in the laboratory. This lesson follows the insulin molecule from the pro-hormone of the body to the product of the factory, and adds the recombinant vaccine.
A child was born without a working gene for an enzyme that the immune system needs. In 1990 her cells were repaired with a normal gene, and this was the first gene therapy. This lesson follows that treatment, and then shows how PCR and ELISA find a disease early.
A transgenic animal carries a gene from another species. Almost all of them are mice, and each kind has its own use: to study genes, to model diseases, to make medicines, and to test vaccines and chemicals. This lesson lists the five uses with the examples that NCERT gives.
