The procedure, in which the nucleus of a somatic cell is inserted into an oocyte, providing the genes for the development of an early-stage embryo, is not yet being performed in the United States.

Hwang's plan provides a possible strategy for accelerating international progress in the field and avoiding some of the legal...
