Genome studies lead to unexpected results

Still, it has been an exciting and promising field. With the acquisition of immense powers to extract, analyze, and synthesize genetic material, or DNA, scientists embarked on an awesome quest to determine the exact sequence of all three billion letters of the genetic code in a human genome. When I graduated with a PhD in genetics in 1961, I never dreamed that we would acquire such capabilities within my lifetime, yet by 2001, the Human Genome Project was complete. Billions of dollars were spent to map the human genome because scientists hoped to find the genes responsible for diseases like cancer, heart disease, and stroke. This knowledge, they thought, would allow them to design specific drugs and maybe even find a way to replace defective genes. For decades, we assumed that the Human Genome Project would reveal a hereditary basis for most diseases, just as they had been...
