Early Thoughts on RNA and the Origin of Life The full impact of the essential role of the nucleic acids in biological systems was forcefully demonstrated by the research community in the 1950s. Although Avery and his collaborators had identified DNA as the genetic material responsible for the transformation of bacteria in 1944, it was not until the early 1950s that the Hershey-Chase experiments provided a more direct demonstration of this role. Finally, the structural DNA double helix proposed by Watson and Crick in 1953 clearly created a structural frame work for the role of DNA as both information carrier and as a molecule that could undergo the necessary replication needed for daughter cells. Research continued by Kornberg and his colleagues in the mid-1950s emphasized the biochemistry and enzymology of DNA replication. At the same time, there was a growing interest in the role of RNA. The 1956 dis covery by David Davies and myself showed that polyadenylic acid and polyuridylic acid could form a double-helical RNA molecule but that it differed somewhat from DN A A large number of experiments were subsequendy carried out with synthetic polyribonucleotides which illustrated that RNA could form even more complicated helical structures in which the specificity of hydrogen bonding was the key element in determining the molecular conformation. Finally, in I960,1 could show that it was possible to make a hybrid helix.

As shown in the text, there can be little doubt that the genetic mechanism is, for all practical purposes, equivalent to life itself. Consequently, it is unrealistic to seek knowledge of the origin of life and its subsequent evolution without si multaneously searching for an understanding of how this apparatus arose and evolved. Fortunately, the annual publication over the recent years of thousandS" of papers dealing with the genetic processes has brought the state of knowledge to a level where a synthesis of their major details in relation to life's history is feasible. Because of the voluminous body of literature, no single book can pos sibly treat all the ramifications of this fundamental subject; subdivision into multiple volumes is necessary. This volume, the first of a trilogy, explores the molecular aspects of the problem in connection with the precellular aspects up to the point of the origin of the cell. The second, currently in progress, is con cerned with the subsequent evolution of the cell as revealed by the energy related organelles and their genetic apparatuses and by ultrastructural details of other cellular parts. The third volume, as presently planned, deals with devel opmental, immunological, and other complexities at the organismic level and, in so doing, throws additional light on basic properties of the genetic processes themselves. Thus, the genetic apparatus provides the warp, and evolution the woof, of the intricate fabric that emerges.

The field of planetary biology and chemical evolution draws together experts in astronomy, paleobiology, biochemistry, and space science who work together to understand the evolution of living systems. This field has made exciting discoveries that shed light on how organic compounds came together to form self-replicating molecules-the origin of life. This volume updates that progress and offers recommendations on research programs-including an ambitious effort centered on Mars-to advance the field over the next 10 to 15 years. The book presents a wide range of data and research results on these and other issues: The biogenic elements and their interaction in the interstellar clouds and in solar nebulae. Early planetary environments and the conditions that lead to the origin of life. The evolution of cellular and multicellular life. The search for life outside the solar system. This volume will become required reading for anyone involved in the search for life's beginnings-including exobiologists, geoscientists, planetary scientists, and U.S. space and science policymakers.

Building on a range of disciplines – from biology and anthropology to philosophy and linguistics – this book draws on the expertise of leading names in the study of organic, mental and cultural codes brought together by the emerging discipline of biosemiotics. The volume represents the first multi-authored attempt to deal with the range of codes relevant to life, and to reveal the ubiquitous role of coding mechanisms in both organic and mental evolution.

The origin of life has been investigated by many researchers from various research fields, such as Geology, Geochemistry, Physics, Chemistry, Molecular Biology, Astronomy and so on. Nevertheless, the origin of life remains unsolved. One of the reasons for this could be attributed to the different approaches that researchers have used to understand the events that happened on the primitive Earth. The origins of the main three members of the fundamental life system, as gene, genetic code and protein, could be only separately understood with these approaches. Therefore, it is necessary to understand the origins of gene, the genetic code, tRNA, metabolism, cell structure and protein not separately but comprehensively under a common concept in order to understand the origin of life, because the six members are intimately related to each other. In this monograph, the author offers a comprehensive hypothesis to explain the origin of life under a common concept. At the same time, the author offers the [GADV] hypothesis contrasting it with other current hypotheses and discusses the results of analyses of genes/proteins and the experimental data available in the exploration of the current knowledge in the field. This book is of interest for science students, researchers and the general public interested in the origin of life.
