A Biochemical Phylogeny of the Protists

A Biochemical Phylogeny of the Protists covers a wide variety of biochemical characters and their usefulness in phylogenetics. This book is composed of 13 chapters that describe the methods of deducing phylogenies of protists from biochemical data. Protists are morphologically simple forms of life, including bacteria, fungi, many algae, protozoa, and sponges. The first chapters deal with the biochemistry, evolution, and phylogenetics of the protists. The subsequent chapters explore the DNA and RNA structure and the protein and enzyme content of some protists. Considerable chapters describe the various metabolic pathways in the protists. The remaining chapters other biochemical processes, including sulfate reduction, nitrogen utilization, and carbon monoxide production. These chapters also provide a summary of numerous research studies biochemical phylogeny. This book will prove useful to biochemists, microbiologists, researchers, and students.
