genetic material that allows selection of successfully changed cells
and instructs the cells to make the desired protein. Methods to
make many copies of stretches of DNA and to determine the
sequence of bases in the DNA allow the researcher to understand
the relationship between DNA sequence and protein product, and
to modify the genetic information of a cell in new and useful
ways. The methods have also been applied to genetically modified
whole plants and animals. Biotechnologists apply these methods
to make useful products for medicine, agriculture, and industry.
This topic will explore some approaches that have proven useful
in health care and some that are still experimental. The possibility
of using this method to create a genetic copy of humans, though
generally viewed as medically too risky, has spurred ethical and
moral debates.
