Textbook Question
Chapter 1, Problem 5CT
In 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a person’s own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwang’s group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?

A controversial issue, closely related to cloning, that has caused a lot of debate is the use of embryonic stem cells. One possible application of these cells is that they may be able to supply replacement tissues to treat diseases such as Parkinson's disease, diabetes, paralysis due to spinal cord injuries, and other degenerative diseases. The word "embryonic", has caused fierce opposition to this type of research because embryos are destroyed when the stem cells are removed. Questions that have surfaced in this debate include: When a cell nucleus is transferred to another cell, have we created life? Does a stem cell have the same status as a human? What should be done with the embryos that are leftover at in vitro fertilization (IVF), clinics? Advocates argue that the medical benefits of stem cell research would be enormous. Opponents argue that life begins at conception and thus this type of research is abortion.

Should cloning be made legal in order to help bring more awareness of the benefits of duplicating stem tissue for research? for example, using it to research uncurable diseases like schizophrenia or spinal cord injuries
Nanotechnology can provide alternatives to early detection of cancer cells, drug delivery, and injectable vaccines that to this day rely on healthcare professionals to administer.
What are the benefits and cost of it?
Which do you think is more equitable in its impact? (benefit or cost) Why?

The mutation leads to a genetic disease. 3. The mutation occurs in sperm cells and is passed to the next generation. 4. The mutation is not discovered or fixed by the cell's enzymes.

Additionally, biotechnology businesses create treatments or procedures (such as DNA fingerprinting). Though its use in medicine and pharmaceuticals is what makes biotechnology most well-known, the science is also used in other fields like genetics, food production, and the creation of biofuels. From this, biotechnology has its origin on where it begin.
