Multiple choice

What is the ethical concern associated with the use of embryonic stem cells?

  1. They are difficult to obtain

  2. They are not effective in treating diseases

  3. They can cause cancer

  4. They involve the destruction of a human embryo
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The use of embryonic stem cells raises ethical concerns because it involves the destruction of a human embryo. This has led to debates about the moral status of embryos and the permissibility of using them for research and therapeutic purposes.

Multiple choice

What is the technique used to reprogram adult cells into pluripotent stem cells?

  1. Gene editing

  2. Tissue engineering

  3. Induced pluripotency

  4. Somatic cell nuclear transfer
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Induced pluripotency is a technique that involves reprogramming adult cells, such as skin or blood cells, into pluripotent stem cells. These cells can then be used to generate various cell types for research and therapeutic applications.

Multiple choice

What is the potential benefit of using induced pluripotent stem cells?

  1. They can be derived from the patient's own cells

  2. They are easier to obtain than embryonic stem cells

  3. They have a lower risk of causing cancer

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Induced pluripotent stem cells offer several potential benefits. They can be derived from the patient's own cells, eliminating the need for donor cells. They are easier to obtain than embryonic stem cells, as they can be generated from a small sample of adult tissue. Additionally, they have a lower risk of causing cancer compared to embryonic stem cells.

Multiple choice

What is the ethical concern associated with the use of tissue engineering technologies?

  1. They can lead to the creation of chimeras

  2. They can be used to create artificial organs that are not compatible with the human body
