Influence of Nucleic Acids on the Synthesis of Crystalline Ca(II), Ba(II), and Sr(II) Silica–Carbonate Biomorphs: Implications for the Chemical Origin of Life on Primitive Earth

The Precambrian era is associated with the origin of life on primitive Earth. It was, in fact, in that era that ribonucleic acid (RNA) was first acquired. From this evolved the genomic deoxyribonucleic acid (DNA) that later generated the biomolecules that formed the first cell. In this way, with the ongoing changes in environmental factors, the first cells evolved to give rise to higher multicellular organisms, i.e., plants and animals....
