New Computer Model Could Explain how Simple Molecules Took First Step Toward Life

Two Brookhaven researchers developed theoretical model to explain the origins of self-replicating molecules.

To understand their work, let’s consider the most famous organic polymer, and the carrier of life’s genetic code: DNA. This polymer is composed of long chains of specific monomers called nucleotides, of which the four kinds are adenine, thymine, guanine, and cytosine (A, T, G, C). In a DNA double helix, each specific nucleotide pairs with another: A with T, and G with C. Because of this complementary pairing, it would be possible to put a complete piece of DNA back together even if just one of the two strands was intact.
