I've been hearing a lot of talk about cloning. What is it, and how does it relate to stem cell research?

Cloning is the process of creating an exact copy of an organism. It’s often used in science to create identical copies of organisms that are already alive. For example, scientists can clone animals like cows and sheep by taking cells from the animal and growing them in a lab dish. The cells divide and multiply until they form a new organism that is genetically identical to the original. This process is called somatic cell nuclear transfer (SCNT).
