Genetic Modification and Insulin Production Quiz

Why is human insulin preferred over pig insulin for diabetics?

• Human insulin has fewer side effects.

• Pig insulin is not as effective as human insulin.

• Human insulin is cheaper to produce.

• Pig insulin is not available in large quantities.

What is the role of bacteria in the production of human insulin?

• Bacteria are used to test the effectiveness of insulin.

• Bacteria are modified to produce insulin as if it were their own protein.

• Bacteria help in the extraction of insulin from human DNA.

• Bacteria are used to store insulin.

What is the first step in the genetic modification process to produce insulin?

• Remove a plasmid from a bacterium.

• Use ligase enzymes to join DNA.

• Incubate bacteria with recombinant plasmid.

• Combine insulin DNA with a plasmid.

Which enzyme is used to cut open the plasmid in the genetic engineering process?

• Restriction enzyme

• Polymerase enzyme

• Helicase enzyme

• Ligase enzyme

What happens after the bacteria take up the recombinant plasmid?

• The bacteria stop reproducing.

• The plasmid is removed from the bacteria.

• The bacteria start producing insulin.

• The bacteria are destroyed.
