Watson and Crick
Francis Crick and
James Watson was a pair of scientist who discovered the structure of DNA, they
uncover the double helix nature. Francis Crick studied physics and received a
BS degree in that branch of science. However Crick was interested in biology
and decided to focus on the effects of x-ray on proteins. James Watson studied
the effect of x-ray on bacteria in the Indiana University and received a degree
in zoology. When the two met, which was by chance, they discovered that they
both wanted to uncover a gene’s true structure. In 1953, after many experiments
with paste and cardboard, they finally figured out that DNA was composed of two
double-helical configurations, however no matter what they did; it always ended
up as a ladder shape. They couldn’t figure what shape was the perfect figure
that allowed genetic information to be protected. They found their missing
puzzle when they saw Franklin’s work and knew that the secret was that the
double helical configuration had to be twisted. Their founding explained how
DNA replicates and how hereditary and genetic information are coded on the DNA.
In 1962, Crick and Watson won the Nobel
Prize in Medicine for discovering the structure of DNA, which became one of the
most important discoveries of the 20th century. Crick then continued
to work in genetic field and later moved into brain research. On the other
hand, Watson, at the American National Institutes of Health, became the
director of the Human Genome Project there.
