  2. To create new drugs from scratch

  3. To improve the efficacy and safety of existing drugs

  4. To reduce the cost of drug production
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Genetic engineering allows scientists to modify the genetic makeup of organisms, such as bacteria or yeast, to produce desired proteins or compounds, which can then be used to develop biopharmaceuticals.

Multiple choice

Which of the following is an example of a genetically engineered biopharmaceutical?

  1. Erythropoietin (EPO)

  2. Human growth hormone (HGH)

  3. Interferon

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Erythropoietin (EPO), human growth hormone (HGH), and interferon are all examples of genetically engineered biopharmaceuticals. These drugs are produced using recombinant DNA technology, which involves the insertion of a gene encoding the desired protein into a host organism.
