Please note: This is a companion version & not the original book. Book Preview:
#1 In 1955, I joined some friends who were going into the Alps. I was asked to join them, and we spent the afternoon walking up to a small restaurant that lay at the base of the huge glacier falling down off the Obergabelhorn.
#2 Francis Crick was a physicist who worked on the three-dimensional structures of proteins. He was thirty-five years old, yet almost totally unknown. He was often not appreciated, and most people thought he talked too much. But his ideas livened up the atmosphere of the lab.
#3 Francis’ theories spread far beyond the confines of protein crystallography. He was always thinking about new experiments, and he would not hide this fact from his colleagues. His friends were unable to hide the fact that a stray remark over sherry might bring Francis smack into your life.
#4 DNA was known to exist in the chromosomes of all cells, and it was believed that all genes were composed of DNA. This meant that proteins would not be the Rosetta Stone for unraveling the secret of life. DNA would have to provide the key to determine how the genes determined color of hair, eyes, and intelligence.
