Beta-turn-driven early evolution: the genetic code and biosynthetic pathways
Abstract:
The physicochemical properties of beta-turns suggest their biological importance prior to the formation of the genetic code. These properties include ones potentially affecting the preference for either L- or D-amino acids. The abundance of certain amino acids in beta-turns is correlated with their assignment to a small, well-defined part of the genetic code and with their role as metabolic precursors for other amino acids. It is proposed that in the prebiotic environment, beta-turns became objects of selection that influenced the evolution of the genetic code and biosynthetic pathways for amino acids.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
