Cloning

Genetic engineering, altering the inherited characteristics of an organism in a
predetermined way, by introducing into it a piece of the genetic material of
another organism. Genetic engineering offers the hope of cures for many
inherited diseases, once the problem of low efficiencies of effective transfer
of genetic material is overcome.

Another development has been the refinement of the technique called cloning,
which produces large numbers of genetically identical individuals by
transplanting whole cell nuclei. With other techniques scientists can isolate
sections of DNA representing single genes, determine their nucleotide sequences,
and reproduce them in the laboratory. This ...

raises a host of issues, "from the fantastic to the profound."

When anesthesia was discovered in the 19th century, there was a speculation that
it would rob humans of the transforming experience of suffering. When three
decades ago, James Watson and Francis Crick unraveled the genetic code, popular
discussion turned not to the new hope for vanquishing disease but to the specter
of genetically engineered races of supermen and worker drones. Later, the
arrival of organ transplants set people brooding about a world of clanking
Frankensteins, welded together made from used parts.

Already there are thousands of frozen embryos sitting in liquid nitrogen storage
around the country. ...
