Abstract Replication is a fundamental process that is critical to life as we know it. While replication today is carried out by complex biochemical machineries that have been evolving for bilhons of years, it must have originated with relatively small molecules in simple systems. Here we explore this concept, focusing on the physicochemical characteristics and prebiotic potential of two classes of biological macromolecules nucleic acids and lipids. We discuss the informational and catalytic capabilities of DNA and RNA, the thermodynamic limits of information transfer, the structure and function of lipid membranes, and the formation and maintenance of primitive protocells . 

As an activator of the phosphokinases, magnesium is essential in energy-requiring biological processes, such as activation of amino acids, acetate, and succinate synthesis of proteins, fats, coen2ymes, and nucleic acids generation and transmission of nerve impulses and muscle contraction (67). 

According to current theories of biological evolution, complex amino and nucleic acids were produced from randomly occurring reactions of compounds thought to be present in the Earth s early atmosphere. These simple molecules then assembled into more and more complex molecules, such as DNA and RNA. Is this process consistent with the second law of thermodynamics Explain your answer.
