The video tutorial explains a process involving a genetic disease where a donor egg is stripped of its DNA and a skin cell is inserted into the egg. Electricity is used to stimulate the egg to divide and form an embryo. Stem cells are then extracted from the embryo, which can be used to grow muscle, liver, and nerve cells. These cells can be transplanted into the original patient without the risk of rejection.

What is the first step in the process of using a donor egg for genetic treatment?

• Stripping the egg of its DNA

• Fertilizing the egg

• Injecting the egg with a virus

• Freezing the egg

How is the egg cell prompted to divide and grow into an embryo?

• By using a chemical solution

• By exposing it to light

• By applying electricity

• By heating it

What type of cells are extracted from the embryo?

• Blood cells

• Stem cells

• Skin cells

• Bone cells

Which of the following can be grown from the extracted stem cells?

• Muscle, liver, and nerve cells

• Skin and hair

• Bone and cartilage

• Blood and lymph

What is the advantage of transplanting cells grown from the patient's own stem cells?

• They are more durable

• There is no risk of rejection

• They grow faster

• They are cheaper to produce
