FAQs on Biotechnological Applications in Medicine: Genetically Engineered Insulin
Q1. What is biotechnology?
Answer: Biotechnology is the use of living organisms or their components to produce products or services. In medicine, this can involve using living cells or genes to treat or prevent disease.
Q2. How is insulin genetically engineered?
Answer: Insulin is a hormone that helps the body control blood sugar levels. People with diabetes don’t produce enough insulin, so they must take it as a medication.
Genetically engineered insulin is made using recombinant DNA technology. This means that the DNA from a human insulin gene is inserted into a bacterium or yeast cell. The cell is then allowed to grow and produce insulin.
Q3. What are the benefits of using genetically engineered insulin?
Answer: There are several benefits to using genetically engineered insulin. First, it is a very pure form of insulin that is less likely to cause allergic reactions. Second, it can be produced in large quantities, so it is generally less expensive than insulin from other sources. Finally, it can betailored to meet the specific needs of individual patients.
Q4. What are the risks of using genetically engineered insulin?
Answer: As with any medication, there are potential risks associated with using genetically engineered insulin. These include allergic reactions, infection, and the development of resistance to the medication. However, these risks are generally considered to be low.
If you have questions about genetically engineered insulin or any other biotechnology applications in medicine, be sure to talk to your doctor. They can help you weigh the risks and benefits to make the best decision for your individual situation
