Part I: General aspects of inheritance Part II: Genetic mapping Part III: Molecular genetics Part IV: Generation of genetic variation Part V: Genes at the population level Course Materials Lecture materials - the slides are an outline of the material; they are not “notes” - develop alternative note-taking strategies - know the outline before class - listen to the lecture during class, taking additional notes to clarify and amplify on the outline Study from a variety of resources - slides, textbook - work the problems from me Part I: General aspects of inheritance Chapter 1 Genetics and the organism Key concept  DNA: hereditary material  DNA: a double helix composed of two intertwined nucleotide chains oriented in opposite direction  Gene (基因): the functional units of DNA  A gene: segment of DNA that can be copied to make RNA  RNA: translated to amino acid sequence of protein  Proteins （蛋白质）: the main determinants of basic structural and physiological properties of an organism  The characteristics of a species: determined by its genes  Variation （变异）within a species: might be determined by hereditary variation, environmental variation, or both 
