This text resource is designed to support reading in the content area. The article describes how researchers at Georgia Tech have discovered that polypeptides, which are the main component of proteins, can be formed by mixing amino and hydroxyl acids, and then simply putting them through wet and dry cycles. This would be a more plausible way for early prebiotic molecules to form. Previously, the only way to produce polypeptides involved boiling temperatures, which are not conducive to life.
