They take the nucleus out of one cell and put it in the next WITH the DNA.
What do scientists do to adult cells to make them behave like embryos?
adult stem cells
Most scientists agree that frozen embryos created through in vitro fertilization should be used to create stem cells, although many people are against it because of their religious views.
Adult stem cells are much less controversial. This is because they do not involve embryos at all. However, adult stem cells cannot differentiate into as many different types of cells as the embryonic stem cell (which can become any type).
Scientists typically obtain embryos used for stem cell research from fertility clinics. These embryos are typically donated by couples who have undergone in vitro fertilization (IVF) and have chosen to donate their unused embryos for research purposes. It is important to note that stem cell research follows strict ethical guidelines and informed consent is obtained from donors.

adult stem cells
A method scientists use to make identical offspring from from adult cells. Do you know, cause I don't?
Scientists believe stem cells from human embryos could hold the key to treatments and cures for disease. Basically it is a debate about stem cell research.

Embryos...
Researchers only use embryos that have been terminated. But using them in research this individual will have had a small part in future research against horrible disease instead of beeing burnt as toxic waste. Embryos are full of omnipotent stem cells. These cells have not yet been turned of and assigned a special function like most cells in an adult body. This is why they are so special. Evern though there are some viable stemcells in an adult, they are very few and are hence not very useful to extract.
An embryonic stem cell potentially can develop into ANY cell in the body theoretically without limit to replenish, and an adult stem cell is only able to mature into a specialised tissue cell from which tissue the cell is positioned.
The controversy surrounding stem cells arises out of the need to use stem cells from embryos which then get destroyed.
