Is it possible to clone a human?

The answer

Technically, the same somatic cell nuclear transfer method used to create Dolly the sheep in 1996 could theoretically apply to humans. However, the process is extremely inefficient - Dolly was the only success from 277 attempts - and cloned animals frequently suffer from premature aging, organ defects, and immune problems. Human reproductive cloning is banned in over 70 countries due to profound ethical concerns and safety risks. Therapeutic cloning of human cells for research purposes is permitted in some jurisdictions under strict regulation.
