A mutation has occurred during mitosis of an individuals bone marrow cell. This event may be the result of the failure of which of the following?

A)

Progenitor cells

B)

Fibroblasts

C)

Stem cells

D)

Cyclins

3.

A patient has experienced a myocardial infarction with accompanying necrosis of cardiac muscle, a permanent tissue. What are the ramifications of the fact that cardiac muscle is a permanent tissue?

A)

The cardiac muscle cells will remain perpetually in the G1 stage of mitosis.

B)

Regeneration of the patients cardiac muscle will be exceptionally slow.

C)

The necrotic cells will be replaced with muscle cells that have limited metabolism.

D)

The cells will not proliferate and will be replaced with scar tissue.

4.

A couple have chosen to pay for the harvesting and storage of umbilical cord blood after the delivery of their child to secure a future source of embryonic stem cells. What is the most likely rationale for the couples decision?

A)

The stem cells may be able to produce a wide range of body cells.

B)

The embryonic stem cells allow stable and permanent tissues to enter mitosis.

C)

The stem cells can change the proliferative capacity of other cells.

D)

The embryonic stem cells remove cyclin-dependent kinase inhibitors from the body.

5.

A)

Prostaglandins

B)

Fibrous structural proteins

C)

Lymphocytes

D)

Water-hydrated gels

E)

Glycoproteins

A)

Hemostasis and vasoconstriction

B)

Keloid formation

C)

Collagen secretion by fibroblasts
