production of hormones or enzymes to replace missing human body chemicals

• DNA is produced from protein absorbed by the cell.

• Protein is composed of DNA that is produced in the cell.

• DNA controls the production of protein in the cell.

• Cells make DNA by digesting protein.

A great deal of information can now be obtained about the future health of people by examining the genetic makeup of their cells. There are concerns that this information could be used to deny an individual health insurance or employment. These concerns best illustrate that

• scientific explanations depend upon evidence collected from a single source

• scientific inquiry involves the collection of information from a large number of sources

• acquiring too much knowledge in human genetics will discourage future research in that area

• while science provides knowledge, values are essential to making ethical decisions using this knowledge
