1
AQ#1: The process of in vitro fertilization
is best described as:
A. Depositing semen into a uterus with a
pipette.
B. Transferring the nucleus of a sperm cell into
an ovum.
C. Sperm fertilizes an ovum in a glass dish.
D. Intercourse occurs at the suspected time of
ovulation.
2
AQ#2: Which of these types of stem cells
can potentially develop into the greatest
number of different types of body cells?
A.
B.
C.
D.
Umbilical cord stem cells
Embryonic stem cells
Adult stem cells
All types are equal
3
AQ#3: Embryonic stem cells are found:
A. In the female reproductive tract
B. In a developing blastocyst
C. In the umbilical cord
D. In a newborn baby
4
AQ#4: A goal of therapeutic cloning in
stem cell research is:
A.
B.
C.
D.
To produce an exact copy of an organism.
To develop new medical treatments.
To produce healthier embryos.
To perfect the genes in the human population.
5
AQ#5: Tissue transplants are difficult due to the lack of
donors and rejection of tissues by the recipient. Which
of the following may become a reality to help solve
these problems?
A.
B.
C.
D.
Remove a healthy cell from the damaged organ, stimulate it to
divide by mitosis in a lab, and replace damaged cells with the new,
healthy cells.
Conceive an embryo using in vitro fertilization, isolate the genes
that stimulate development of specific types of cells, make multiple
copies of these genes and insert them back into the embryo, and
the embryo will now develop into a specific tissue rather than an
entire organism.
Clone a zygote from a patient’s body cell, allow it to develop into a
blastocyst, remove a few embryonic stem cells, and induce these
to develop into new tissue.
It will never be possible to grow tissue in artificial (laboratory)
conditions.
6
AQ#6: Which of the following conditions
is the best candidate for treatment by
stem cell therapy?
A. Trisomy 21
B. Parkinson’s disease
C. Mononucleosis
D. Appendicitis
