一、历史回顾 140年前, Mendel在捷克莫勒温镇一个修道院里沉醉于豌豆杂交实验,也许根本就没有想到,他提出的遗传因子在半个世纪后被 Morgan定义为基因。1944 Avery年证明了基因的物质基础是DNA50年代 WatsonCrick初和又揭示了DNA的分子结构70年代初,DNA已可在体外被随意拼接并转回到细菌体内遗传和表达

Virus have both an extracellular and an intracellular state. A virus is a submicroscopic particle containing nucleic acid surrounded by protein and occasionally containing other macromolecular components. In this extracellular state, the virus particle, also called the virion, is metabolically inert and does not carry out respiratory or biosynthetic

Mutualism Symbiosis is an obligatory interrelationship between two populations that benefits both of them Lichens is composed of a fungus and an alga

Methods in Microbial Ecology Microbial ecology focus on two major issues: (1) biodiversity, including the isolation, identification, and quantification of microorganisms in various habitats, and (2) microbial activity, that is, what are microorganisms doing in their habitats. We begin here with a consideration of assessing biodiversity through enrichment and isolation, and then consider nonculture methods of identification

Transcriptional Regulation in Bacteria Thanks to the relative ease of doing genetics with bacteria, transcriptional regulation in bacteria is better understood than that in other organisms and has served as a framework for understanding transcriptional regulation in eukaryotic organisms
