Synopsis: Could amino acids, floating in the oceans of the primordial Earth, have assembled themselves into protein molecules without DNA? This is the question that evolutionary biologist, Dean Kenyon, confronted 40 years ago. Kenyon’s search for an answer led him to explore the structure of the DNA molecule and the biological information stored in its double helix. This information has been called the “language of life,” for it contains the genetic blueprint necessary to build every living organism on the planet. Kenyon was challenged to explain how the first proteins could have self-assembled without the help of genetic instructions. Today, scientists face some of the same challenges that Kenyon encountered. How can Natural Selection explain the origin of the information in the DNA molecule? |
