9:(1-2) The possibility of human cloning, raised when Scottish
scientists at Roslin Institute created the much-celebrated sheep
"Dolly" (Nature 385, 810-13, 1997), has aroused worldwide
interest and concern because of its scientific and ethical
implications. The feat, cited by Science magazine as the
breakthrough of 1997, also has generated uncertainty over the
meaning of "cloning" --an umbrella term traditionally used by
scientists to describe different processes for duplicating
biological material. Cloning DNA, Cells, and Animals To Human
Genome Project researchers, cloning refers to copying genes and
other pieces of chromosomes to generate enough identical
material for further study. Cloned collections of DNA molecules
(called clone libraries) enable scientists to produce
increasingly detailed descriptions of all human DNA-
