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 offers the possibility of creating
entirely new genes with commercially or medically desirable properties.

While the potential benefits of genetic engineering are considerable, so may be
the potential dangers. For example, the introduction of cancer-causing genes
into a common infectious organism, such as the influenza virus, could be
hazardous.
