Final answer:
Cloning can be carried out using both adult stem cells and embryonic stem cells. Adult stem cells have a limited range of differentiation, while embryonic stem cells are pluripotent, meaning they can develop into various cell types. Induced pluripotent stem cells (iPSCs) are another type of stem cells that are similar to embryonic stem cells and can be derived from adult stem cells.
Step-by-step explanation:
In the case of cloning, adult stem cells are not the only type of cells that can be used. The technology used to produce Dolly, the first cloned mammal, involved introducing DNA from an adult cell into an egg cell and stimulating it to divide. The resulting cells, called embryonic stem cells, have the potential to develop into various types of cells in the body. Adult stem cells, on the other hand, are already specialized and have a limited range of differentiation.
While adult stem cells can be obtained from various organs and tissues, embryonic stem cells have the advantage of being pluripotent, meaning they can give rise to many different cell types. However, there are ethical and legal concerns associated with the use of embryonic stem cells. As an alternative, induced pluripotent stem cells (iPSCs) have been developed from adult stem cells, which share similar characteristics with embryonic stem cells.
