Question

The following summer, after his freshman year at Harvard
University, Ebright went back to the laboratory of the Department of
Agriculture and did more work on the hormone from the gold spots.
Using the laboratory's sophisticated instruments, he was able to
identify the hormone's chemical structure.
A year-and-a-half later, during his junior year, Ebright got the idea
for his new theory about cell life. It came while he was looking at X-ray
photos of the chemical structure of a hormone.
When he saw those photos, Ebright didn't shout, 'Eureka!' or even,
I've got it! But he believed that, along with his findings about insect
hormones, the photos gave him the answer to one of biology's puzzles:
how the cell can read the blueprint of its DNA. DNA is the substance
in the nucleus of a cell that controls heredity. It determines the form
and function of the cell. Thus DNA is the blueprint for life.
