The DNA does not construct either the pancreas or the brain. DNA is
a set of specifications for making proteins. A blueprint does not
construct a house or anything else, but carpenters and bricklayers
may use the blueprint in carrying out their construction. DNA
doesn't construct anything. The machinery of the living cell
constructs, and uses the DNA in the construction.
