Genetic Engineering and Insulin Production

Professor Jean introduces PR, who needs insulin due to diabetes. The video explains organisms, cells, and DNA, highlighting how genes determine characteristics like eye color and height. It describes genetic modification, focusing on extracting the insulin gene using restriction enzymes. The insulin gene is inserted into bacteria using plasmids and ligase, creating genetically modified organisms that produce insulin. This insulin is used to help people with diabetes, like PR, stay healthy.

What is the primary reason PR is unhappy?

• He has diabetes and needs insulin.

• He doesn't like school.

• He lost his favorite toy.

• He is afraid of the dark.

Which of the following is NOT considered an organism?

• A flower

• A human

• A rock

• A tree

What part of the cell contains the information that makes you unique?

• The cytoplasm

• The DNA

• The mitochondria

• The cell membrane

Which gene is responsible for determining your height?

• Hair color gene

• Eye color gene

• Height gene

• Insulin gene

What tool do scientists use to cut DNA at specific sections?

• Restriction enzymes

• Plasmids

• Ligase

• Microscopes

What shape is some of the DNA found in bacteria?

• Triangular

• Square

• Hexagonal

• Circular

What enzyme acts like glue to help insert the insulin gene into a plasmid?

• Ligase

• Restriction enzyme

• Polymerase

• Helicase

What happens to bacteria after they are genetically modified with the insulin gene?

• They change color.

• They become harmful.

• They produce human insulin.

• They stop reproducing.

Why is the insulin produced by genetically modified bacteria important?

• It helps plants grow faster.

• It is used to treat people with diabetes.

• It makes bacteria glow in the dark.

• It is used as a food preservative.

What is the final outcome of the process described in the video?

• Production of human insulin for diabetes treatment.

• Discovery of a new planet.

• Creation of a new species of bacteria.

• Development of a new type of plant.
