Molecular Biology Unit Exam Question 1 Consider the following origin of replication that is found on a chromosome. The sequence of region 1 is shown below. Region 1: 5??CTGACTGACA?3? 3??GACTGACTGT?5? 3? 5? 5? 3? Region 1 top ? ori bottom ? a) Within Region 1, which strand will be the template for leading strand synthesis, the top or the bottom? b) If we assume that a lagging strand fragment is made from region 1, what will be its sequence? c) You examine DNA replication in an E. coli mutant, which has a partially defective DNA polymerase. In vitro experiments using the mutant DNA polymerase gives an error rate of 10-3, as compared to the expected error

Campbell's Biology, 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5, the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers, and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure, because this is central to understanding subsequent chapters on metabolism, molecular biology, and molecular medicine. Multiple-Choice Questions 1) Humans and mice differ because A) their cells have different small organic molecules. B) their cells make different types of large biological molecules.

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

Lectures by Erin Barley Kathleen Fitzpatrick From Gene to Protein Chapter 17 Overview: The Flow of Genetic Information ? The information content of DNA is in the form of specific sequences of nucleotides ? The DNA inherited by an organism leads to specific traits by dictating the synthesis of proteins ? Proteins are the links between genotype and phenotype ? Gene expression, the process by which DNA directs protein synthesis, includes two stages: transcription and translation ? 2011 Pearson Education, Inc. Concept 17.1: Genes specify proteins via

Chapter 15 The Chromosomal Basis of Inheritance Lecture Outline Overview: Locating Genes on Chromosomes Genes are located on chromosomes. Concept 15.1 Mendelian inheritance has its physical basis in the behavior of chromosomes Around 1900, cytologists and geneticists began to see parallels between the behavior of chromosomes and the behavior of Mendel?s factors. Using improved microscopy techniques, cytologists worked out the process of mitosis in 1875 and meiosis in the 1890s. Chromosomes and genes are both present in pairs in diploid cells. Homologous chromosomes separate and alleles segregate during meiosis. Fertilization restores the paired condition for both chromosomes and genes.
