  1. Gene augmentation

  2. Gene silencing

  3. Gene editing

  4. Gene replacement

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Gene augmentation involves introducing a functional gene into a cell to compensate for a defective gene, while gene silencing, gene editing, and gene replacement all involve modifying or replacing a defective gene.

Multiple choice

Which of the following is NOT a potential application of gene therapy?

  1. Treating genetic disorders

  2. Developing new vaccines

  3. Curing cancer

  4. Enhancing athletic performance

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gene therapy is primarily used for treating genetic disorders, developing new vaccines, and curing cancer. Enhancing athletic performance is not a legitimate application of gene therapy.

Multiple choice

Which type of gene therapy involves replacing a defective gene with a functional copy?

  1. Gene augmentation

  2. Gene silencing

  3. Gene editing

  4. Gene replacement

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gene replacement therapy involves replacing a defective gene with a functional copy, either by directly inserting the functional gene into the genome or by using a viral vector to deliver the gene to the target cells.

Multiple choice

Which type of gene therapy involves using a viral vector to deliver a functional gene to target cells?

  1. Gene augmentation

  2. Gene silencing

  3. Gene editing

  4. Viral vector-mediated gene transfer

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Viral vector-mediated gene transfer involves using a modified virus to deliver a functional gene to target cells. The virus is engineered to be non-replicative and to carry the therapeutic gene, which is then integrated into the host cell's genome.

Multiple choice

What is the main advantage of using gene therapy over traditional drug therapy?

  1. It can target the underlying genetic cause of a disease

  2. It has fewer side effects

  3. It is more effective in treating chronic diseases

  4. It is less expensive to administer

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Gene therapy has the potential to target the underlying genetic cause of a disease, offering the possibility of a permanent cure. Traditional drug therapy often only treats the symptoms of a disease, not the underlying cause.
