Watson and Crick's DNA discovery turns 50

"Before Watson and Crick made their breakthrough, scientists knew that the DNA molecule was made of a few relatively simple chemicals. They had the recipe for DNA, but no-one was sure how these simple chemicals combined to carry the huge amount of information required to recreate a living thing. Instead of carrying out experiments, Watson and Crick set out to think their way out of the problem."
