Campbell's Biology, 9e (Reece et al.) Chapter 1 Introduction: Themes in the Study of Life This introductory chapter explores the basic themes and concepts of biology, with emphasis on the core theme of evolution. It also introduces students to the thinking of scientists. Questions are therefore general; however, an effort has been made to include some from each skill level. As in the rest of this test bank, questions that feature art or those for which several questions follow upon some data or a scenario are placed together at the end of the chapter. Multiple-Choice Questions 1) A localized group of organisms that belong to the same species is called a A) biosystem. B) community. C) population. D) ecosystem. E) family. Answer: C Topic: Concept 1.1

August 2013 Chapter 23 The Evolution of Populations 23.1 Population genetics provides a foundation for studying evolution Darwin and Mendel were contemporaries of the 19th century At the time both were unappreciated for their work Microevolution ? the generation-to-generation change in the population?s frequencies on alleles The Modern Synthesis The turning point for revolutionary theory was the development of population genetics Population Genetics ? Study on how a population changes over time Emphasizes genetic variation and recognizes the importance of quantitative characters Gene Pools and Allele Frequencies A population?s gene pool is defined by it?s allele frequencies (quantity of alleles in a population) Population ? a group of organism that belong to the same species

4/2/13 1:14 PM DNA Deoxyribose Double Stranded (Double Helix) Nitrogenous bases (Cytosine, Guanine, Adenine, Thymine) RNA Ribonucleic Single Stranded Nitrogenous bases (Cytosine, Guanine, Adenine, Uracil) Both have phosphate Cytosine = Guanine Adenine = Thymine DNA Replication is semi conservative. DNA Replication happens during interphase. One strand determines the sequence of the other strand. DNA polymerase copies DNA strands in the 5?->3? direction. Transcription ? The first step of gene expression, in which a particular segment of DNA is copied into RNA by the enzyme, RNA polymerase. Translation ? The process through which cellular ribosomes manufacture proteins. In DNA, T=A G=C In RNA, T=A G=C A=U Translation occurs in the cytoplasm.

2/27/13 1:16 PM Sisterchromatids ? 2 identical copies of a chromosome/chromatin attached at a centromere. Meiosis 2 divisions called meiosis I and meiosis II. During Meiosis I Crossing over ? exchanges genetic information between homologous chromosomes. Independent assortment ? Line up randomly and separate into daughter cells Both increase genetic diversity in sexual reproduction. During Meiosis II Sisterchromatids divide Final Result 4 cells, haploid genetically different from original cell. Mitosis and Meiosis 2/27/13 1:16 PM 2/27/13 1:16 PM
