Biotechnology and Genetic Engineering Concepts

What was the primary issue with using animal-derived insulin for diabetes treatment?

• It triggered immune responses and inflammation.

• It was chemically identical to human insulin.

• It was too expensive to produce.

• It was difficult to extract from animals.

Which enzyme is responsible for cutting DNA at specific sequences during genetic engineering?

• RNA polymerase

• Restriction enzymes

• DNA ligase

• Helicase

What is the purpose of inserting a gene into a plasmid during recombinant DNA technology?

• To create a new type of bacteria.

• To prevent bacterial reproduction.

• To enable bacteria to produce the desired human protein.

• To increase the size of the DNA molecule.

What is interferon beta primarily used to treat?

• Blood clots

• Diabetes

• Multiple sclerosis

• Hemophilia

What is the role of a master cell bank in recombinant drug production?

• It handles the packaging of the final product.

• It tests the drug for effectiveness.

• It monitors the production process for errors.

• It stores the original cells containing the desired gene.
