Cloning: can it be good for us? An overview of cloning technology and its moral implications.
Adequate answers to moral questions about cloning require a working knowledge of the science and technology involved, both present and anticipated. This essay presents an overview of the current state of somatic cell nuclear transfer technology (SCNT), the type of cloning that now permits whole organism reproduction from adult DNA. This essay explains the basic science and technology of SCNT and explores its potential uses. Next, this essay notes remaining scientific obstacles and unanswered moral questions that must be resolved before SCNT can be used for human reproduction. Attention is given to aspects related to cloning for therapeutic and research purposes.
