Adult cell cloning

• What should you know after studying adult cell cloning?

  You should know how adult cell cloning is carried out and the benefits and risks of adult cloning.
• How do small invertebrates like hydra reproduce?

  They reproduce asexually in a way similar to plants.
• Can reptiles reproduce asexually?

  Yes, some reptiles can reproduce asexually with eggs that do not need to be fertilized.
• Do mammals reproduce asexually?


  No, mammals never reproduce asexually.
• What is adult cell cloning considered in the context of scientific breakthroughs?

  It is considered a major scientific breakthrough.
• What is the process of adult cell cloning?

  It involves taking a cell from an adult animal and making an embryo from it.
• Who was the first mammal to be cloned from another adult mammal?


  Dolly the sheep.
• What happened to Dolly after she was cloned?

  She went on to have lambs of her own in the normal way.
• What are the steps involved in adult cell cloning?

  1. Remove the nucleus from an unfertilized egg cell.

  2. Insert the nucleus from an adult body cell into the empty egg cell.

  3. Apply a small electric shock to stimulate division.

  4. Insert the developing embryo into the womb of an adult female.
• What does the embryo contain in adult cell cloning?

  The embryo contains the same genetic information as the adult skin cells.
• What is one benefit of adult cell cloning?

  It may help to bring back animals from extinction.
• What is a concern regarding the cloning of human babies?

  It could be abused and lead to ethical issues.
• What is a potential risk of adult cell cloning related to genetic diversity?

  It reduces genetic diversity, making populations less able to survive changes.
• What are the main steps in adult cell cloning?

  1. Remove the nucleus from an unfertilized egg cell.

  2. Insert the nucleus from an adult body cell.

  3. Stimulate the egg cell to divide.

  4. Insert the embryo into the womb of an adult female.
• What is the main problem with modern cloning techniques?

  They produce many plants or animals with identical genes.
• Why is it problematic to have cloned organisms with identical genes?

  It makes the population less able to survive environmental changes.
• What is the first step in adult cell cloning?

  The nucleus is removed from an unfertilized egg cell.
• What stimulates the egg cell to divide in adult cell cloning?

  A small electric shock.
• What happens when the embryo develops into a ball of cells?


  It is inserted into the womb of an adult female to continue its development.
• What type of cell is used to create an embryo in adult cell cloning?

  An adult body cell, such as a skin cell.
• What is the significance of the genetic information in the embryo created through adult cell cloning?

  It is identical to that of the adult skin cells used.
