cell division

Question 1

what is therapeutic cloning

Answer 1

a cloning method where an embryo is produced with the same genetic makeup as the patient

• the stem cells which originate from the embryo will not be rejected from the patients immune system so can be used to treat certain medical conditions.

Question 2

advantages of cloning plants using meristem stem cells

Answer 2

• can prevent rare plants from being extinct
  -can produce a large amount of plants with favourable characteristics.
  -can produce identical plants for research

Question 3

what are the issues associated with embryonic stem cells

Answer 3

• many embryonic stem cells are sourced from aborted embryos some people have ethical or religious objection.
• development of stem cell therapies is slow ,expensive and difficult

-adult stem cell infected with viruses could pass them on to the patient

-if donor stem cells do not have similar makeup to the patient and immune response could be triggered.
