BIOL240 Lecture Notes - Lecture 1: Transfer Rna, Helicobacter Pylori, Lipid Bilayer
Document Summary
Microbiology is the study of microbes: examine how microbes interact with humans, food, and how they can be used by humans. Why study microbiology? microorganisms: our understanding of life has arisen largely from studies of. Continue to contribute to fundamental knowledge of life processes. The basis for life: metabolism (energy -> atp, growth, reproduction, genetic variation/evolution, response/adaptation to the external environment, homeostasis (maintaining internal organization and order, usually by expending energy) Polypeptides are the building blocks for enzymes and other proteins. The lipid bilayer: separates cell interior from the external environment, often embedded with polysaccharides and polypeptides. Nucleic acids: dna and rna, critical as storehouses of genetic information. Classifying microbes (until 1970"s): prokaryotic ( pre-kernel ) and eukaryotic: divided into three domains based on ribosomal rna sequences ( kernel . Them!!!: each of the three domains has some similarities and difference (know.
