Stem Cells:Promises to Keep? Assessment Questions By William D. Rogers Ball State University Adapted from a case by Lauren E. Yaich
AQ#1: The process of in vitro fertilization is best described as: • Depositing semen into a uterus with a pipette. • Transferring the nucleus of a sperm cell into an ovum. • Sperm fertilizes an ovum in a glass dish. • Intercourse occurs at the suspected time of ovulation.
AQ#2: Which of these types of stem cells can potentially develop into the greatest number of different types of body cells? • Umbilical cord stem cells • Embryonic stem cells • Adult stem cells • All types are equal
AQ#3: Embryonic stem cells are found: • In the female reproductive tract • In a developing blastocyst • In the umbilical cord • In a newborn baby
AQ#4: A goal of therapeutic cloning in stem cell research is: • 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.
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? • 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.
AQ#6: Which of the following conditions is the best candidate for treatment by stem cell therapy? • Trisomy 21 • Parkinson’s disease • Mononucleosis • Appendicitis
