A majority of evolutionary biologists believe that we now can envision our biological predecessors--not the first, but nearly the first, living beings on Earth. This book is about these vanished forebears. The era between the first rudimentary life on Earth and the appearance of more complex beings is called the RNA world. It is RNA (ribonucleic acid) long believed to be a mere biologic copier and messenger, that offers a glimpse into our ancient predecessors. To describe early RNA creatures, here called "ribocytes" or RNA cells, the author uses basics of molecular biology. He reviews our current understanding of the tree of life, examines the structure of RNA itself, explains the operation of the genetic code, and more. Courting controversy among those who question the role of ribocytes -- citing the chemical fragility of RNA and the uncertainty about the origin of an RNA synthetic apparatus -- he offers a vision of early life on Earth.

This laboratory guide represents a growing collection of tried, tested and optimized laboratory protocols for the isolation and characterization of eukaryotic RNA, with lesser emphasis on the characterization of prokaryotic transcripts. Collectively the chapters work together to embellish the RNA story, each presenting clear take-home lessons, liberally incorporating flow charts, tables and graphs to facilitate learning and assist in the planning and implementation phases of a project.RNA Methodologies, 3rd edition includes approximately 30% new material, including chapters on the more recent technologies of RNA interference including: RNAi; Microarrays; Bioinformatics. It also includes new sections on: new and improved RT-PCR techniques; innovative 5' and 3' RACE techniques; subtractive PCR methods; methods for improving cDNA synthesis.* Author is a well-recognized expert in the field of RNA experimentation and founded Exon-Intron, a well-known biotechnology educational workshop center * Includes classic and contemporary techniques * Incorporates flow charts, tables, and graphs to facilitate learning and assist in the planning phases of projects

Some 3.8 billion years ago, in an era of churning seas and murky skies, a few chemicals combined under the right conditions, and life emerged on planet Earth. From that first cell, life progressed to a myriad of one-celled organisms, to organisms capable of photosynthesis, to multicellular organisms, to simple plant and animal forms, up to the complex life-forms we know today. The Evolution of Cells, Third Edition traces these developments and how they may have occurred, through the scientific study of fossils, relationships among organisms, biochemistry of current life-forms, genetic sequencing, and laboratory experiments. Readers will also explore the complexity of cells and the ways science is making use of internal cell mechanisms for new discoveries in sustainable energy sources, cleaning up pollution, improving the food supply, and treating disease.

This highly interdisciplinary book discusses the phenomenon of life, including its origin and evolution, against the background of thermodynamics, statistical mechanics, and information theory. Among the central themes is the seeming contradiction between the second law of thermodynamics and the high degree of order and complexity produced by living systems. As the author shows, this paradox has its resolution in the information content of the Gibbs free energy that enters the biosphere from outside sources. Another focus of the book is the role of information in human cultural evolution, which is also discussed with the origin of human linguistic abilities. One of the final chapters addresses the merging of information technology and biotechnology into a new discipline — bioinformation technology.This third edition has been updated to reflect the latest scientific and technological advances. Professor Avery makes use of the perspectives of famous scholars such as Professor Noam Chomsky and Nobel Laureates John O'Keefe, May-Britt Moser and Edward Moser to cast light on the evolution of human languages. The mechanism of cell differentiation, and the rapid acceleration of information technology in the 21st century are also discussed.With various research disciplines becoming increasingly interrelated today, Information Theory and Evolution provides nuance to the conversation between bioinformatics, information technology, and pertinent social-political issues. This book is a welcome voice in working on the future challenges that humanity will face as a result of scientific and technological progress.

Investigating Seafloors and Oceans: From Mud Volcanoes to Giant Squid offers a bottom-to-top tour of the world's oceans, exposing the secrets hidden therein from a variety of scientific perspectives. Opening with a discussion of the earth's formation, hot spots, ridges, plate tectonics, submarine trenches, and cold seeps, the text goes on to address such topics as the role of oceans in the origin of life, tidal bore, thermal effects, ecosystem services, marine creatures, and nutraceutical and pharmaceutical resources. This unique reference provides insight into a wide array of questions that researchers continue to ask about the vast study of oceans and the seafloor. It is a one-of-a-kind examination of oceans that offers important perspectives for researchers, practitioners, and academics in all marine-related fields. - Includes chapters addressing various scientific disciplines, offering the opportunity for readers to gain insights on diverse topics in the study of oceans - Provides scientific discussion on thermo-tolerant microbial life in sub-seafloor hot sediments and vent fields, as well as the origin of life debates and the puzzles revolving around how life originated - Includes detailed information on the origin of dreaded episodes, such as volcanic eruptions, earthquakes, tsunamis, internal waves and tidal bores - Contains information on the contribution of the oceans in terms of providing useful nutraceutical and pharmaceutical products
