Worksheet: Modern Advances in Medicine

In this worksheet, we will practice discussing the risks and benefits of modern advances in medicine such as stem cells, gene technology and the human genome project.

Q1:

Which of the following is a correct limitation of gene therapy?

  • AGenetic disorders, like cystic fibrosis, cannot be treated using gene therapy.
  • BGene therapy can currently only be used to target cells in gametes.
  • CGene therapy cannot be used in conjunction with other medicines.
  • DThe treatment has to be repeated as cells in the body are continually replaced.

Q2:

Determine whether the following are arguments for or against the use of gene technology in medicine.

Knowing that someone is going to develop a disease may lead to an increase in their health insurance or medical fees.

  • AArgument for
  • BArgument against

Understanding how genes interact with medicines will help in developing more effective treatments.

  • AArgument against
  • BArgument for

Gene technology is a relatively new area of research and we do not know its potential long-term effects.

  • AArgument against
  • BArgument for

Q3:

Which of the following best describes gene therapy?

  • AGene therapy is the placement of functional alleles into cells that contain faulty alleles.
  • BGene therapy is the sequencing of a person’s genome to determine what alleles are faulty.
  • CGene therapy is the placement of faulty alleles into cells that contain functional alleles.
  • DGene therapy is the replacement of all nonfunctional alleles within a person’s genome.

Q4:

Which of the following is a reason scientists are developing the use of embryonic stem cells in medicine?

  • AEmbryonic stem cells can be used to develop new cellular functions.
  • BEmbryonic stem cells are easy to work with and differentiate quickly.
  • CEmbryonic stem cells are cheap and easy to obtain.
  • DEmbryonic stem cells can differentiate into any type of cell.

Q5:

If someone is suffering from kidney failure, they may be offered an organ transplant with a donated kidney from another person. Which of the following is a disadvantage of undergoing an organ transplant?

  • AThe cells in the donated kidney could divide out of control and cause cancer.
  • BThe host body may recognize the donated organ as foreign and try to attack it.
  • CTransplanted organs typically only last 12–16 months before they need replacing.
  • DThe patient will have to undergo many hours of dialysis treatment a week.

Q6:

The graph provided shows the number of organ transplants successfully performed per year (blue) compared to the number of people needing a transplant (red). Which of the following statements about the graph is correct?

  • AThe number of people requiring an organ transplant since 1995 has steadily increased.
  • BThe number of organ transplants performed since 1995 has decreased.
  • CThe number of people requiring an organ transplant since 1995 has steadily decreased.
  • DThe number of people requiring an organ transplant since 1995 has remained constant.
  • EThe number of organ transplants performed since 1995 has increased.

Q7:

Complete this statement: The drugs given to the recipient of an organ transplant to reduce the risk of rejection are called drugs.

  • Aimmunostatic
  • Bimmunorejecting
  • Cimmunosuppressant
  • Dimmunocidal

Q8:

The diagram provided shows a basic outline of gene therapy.

For the following statements, fill in the blanks with the most appropriate term.

In the first step of gene therapy, a functional for the affected gene is removed from donor DNA.

  • Agenotype
  • Ballele
  • Cnucleotide
  • Dorgan

This is then placed into a modified .

  • Acell from the patient
  • Bfungus
  • Cgenome
  • Dvirus

The modified is injected into the of the person with the faulty gene.

  • Apatient cell, organs
  • Bvirus, body
  • Cgenome, organs
  • Dfungus, cells

The functional is taken in and by the body cells.

  • Achromosome, demonstrated
  • Bvirus, digested
  • Callele, expressed
  • Dgenome, expressed
