People suffering from diabetes need to be injected with insulin in order to keep their blood glucose levels stable. In the early 1900s, insulin for diabetes patients was extracted from slaughtered cows and pigs. However, in the 1970s, genetic engineering technology allowed scientists to engineer a bacterium to produce human insulin.

There are no benefits to this form of biotechnology.
|
|
|
Genetically engineered bacteria cannot become pathogenic to humans.
|
|
|
Patients with diabetes now have a steady, inexpensive supply of insulin available.
|
|
|
There is no longer a large market for cow and pig organs.

Explanation:
Detailed explanation-1: -Hint: Human insulin can be produced by inserting the human insulin gene into the plasmid, putting the plasmid into bacteria, and putting the “recombinant” bacteria in fermentation tanks. There, the bacteria begin producing human insulin.
Detailed explanation-2: -The possible benefits of genetic engineering include: More nutritious food. Tastier food. Disease-and drought-resistant plants that require fewer environmental resources (such as water and fertilizer)
