Stem Cell Research and Cloning: Advancements and Limitations

The video discusses the state of stem cell research, highlighting that it is permitted in Britain but banned in many other countries due to ethical concerns. It explains the potential of embryonic stem cells to develop into any specialized cell and the possibility of cloning them to regenerate damaged organs. This could lead to organ transplants that are not rejected by the body. However, the benefits of such research may not be realized for several years.

In which country is research using human stem cells permitted?

• United States

• Britain

• Canada

• Australia

What is a key characteristic of embryonic stem cells?

• They can develop into any specialized cell type.

• They can only develop into muscle cells.

• They are identical to adult cells.

• They are used only for cloning.

What does it mean for a clone to be genetically identical?

• It is similar but not identical to its parent.

• It shares the same genetic material as its parent.

• It has no genetic material.

• It has a different genetic makeup than its parent.

What is a potential benefit of using cloned embryonic cells for organ regeneration?

• The new organ will be identical to a donor organ.

• The new organ will not be rejected by the body.

• The new organ will have a different genetic blueprint.

• The new organ will be rejected by the body.

What do researchers emphasize about the benefits of their work with stem cells?

• Benefits will be immediate.

• Benefits are guaranteed.

• Benefits are not expected.

• Benefits may take years to be realized.
