Stem Cells And Therapuetic Cloning

Question 1

Evaluate the use of stem cells from embryos or adult bone marrow for treating human disease

Answer 1

Embryonic stem cells treat variety of disease
Embryonic are more available
Embryonic can become more cell types than adult

Bone marrow has no ethical issues
Adult is quick recovery
Has a higher success rate

Adult has limited range

Question 2

Where can stem cells be found in plants

Answer 2

Meristems

Question 3

Name one major difference between embryonic stem cells and adult stem cells.

Answer 3

Embryonic stem cells can differentiate into any type of human body cell but adult stem cells can only differentiate into certain types of body cell.

Question 4

Explain why some people agree and some people disagree with using embryonic stem cells for medical research and treatment?

Answer 4

embryos are potential human lives and therefore it would be wrong to use them for research and treatments whereas others believe that curing ill people is more important that the rights of the embryos

Question 5

Discuss the uses of cloning in plants

Answer 5

Prevent extinction

Disease resistance

Create large amounts of

Increase farmer profits

Question 6

What are the steps of therapeutic cloning

Answer 6

Nucleus removed from cell

Nucleus is removed from donors egg cell and discarded

Patient nucleus transferred to empty donor egg cell

Mitosis happens and cell divides to form embryos

Stem cells removed from embryos and cultured to make more

Differentiate into any cell types

Question 7

Advantages of therapeutic cloning

Answer 7

Treat different medical conditions

Cells Less likely to be rejected

Question 8

Disadvantages of therapeutic cloning

Answer 8

Potential life destroyed

Shortage of donors

Viral infections
