Description
Today we are still far from having a compelling understanding of how life started on Earth or of the probability of the existence of life elsewhere in the universe. Life as we know it on Earth is based on carbon chemistry of three types of compound classes: DNA and RNA that are involved in transcript and translation of the genetic code, proteins that act as functional units such as enzymes and amphiphilic compounds that are the major components of membranes. One of the central questions in the study of the origin of life is what kind of prebiotic chemistry has led to the evolution of self-organizing systems and eventually to life. This session invites papers that discuss the role of organic chemistry in the emergence of life as well as theoretical models and experiments that investigate the transition from nonliving to living matter.
