Explanation:

Genetic Engineering is the process which involves the manipulation of genetic material of an organism to get beneficial traits.

Genetic engineering can be used in the field of medicine to produces hormones( insulin), vaccines, and antibiotics (amoxicillin) et cetera. These substances can be produced in genetically engineered microorganisms by altering their genetic material.
