LECTURE PRESENTATIONS For CAMPBELL BIOLOGY, NINTH EDITION Jane B. Reece, Lisa A. Urry, Michael L. Cain, Steven A. Wasserman, Peter V. Minorsky, Robert B. Jackson ? 2011 Pearson Education, Inc. 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

Nutrition In order for the human body to be healthy and resistant to disease, good nutrition is required. All living things are made of chemicals. In order to grow, develop and maintain bodily structures and functions, specific chemicals must be acquired from the food we eat. In a sense, we are what we eat. Nutrients can be divided into the following categories: Nutrients Overview Carbohydrates ? sugar based molecules that are metabolized for energy in cellular respiration and make up the structural components of plant cell walls. Lipids ? fat based molecules that store large quantities of energy. These molecules also make up the structure of cell membranes.

David Kim 4/2/14 Dr. Oliveira AP Biology All cells have plasma membranes, cytosol, chromosomes and ribosomes. Prokaryotic cells do not have nuclei so the genetic information is in what is called the nucleoid. Prokaryotes also lack membrane bound organelles. Eukaryotic cells have genetic information known as DNA bound by a nuclear envelope. They also have membrane bound organelles like the Endoplasmic Reticulum and Golgi apparatus.

Chapter 11 Notes Trini Soza Feeding the World ? A farm where animals do most of the work. Rapidly growing population needs rapidly produced food. Human nutritional requirements are not always satisfied Humans used to survive on hunting and gathering, but 10,000 years ago agriculture began. Advances in agriculture have improved the human diet Tremendous gains in agriculture productivity and food distribution were in the 20th century. Despite advances, to this day, 24,000 people starve to death each day. 8.8 million each year. Nutritional Requirements Undernutrition: Not consuming enough calories to be healthy Food calories are converted into usable energy for the human body. Not receiving enough calories leads to an energy deficit

Chapter 1 Describe the hindsight bias and explain how it often leads us to perceive psychological research as merely common sense. Compare and contrast case studies, surveys, and naturalistic observation, and explain the importance of proper sampling. Explain why correlational research fails to provide evidence of cause-effect relationships. Identify the basic elements of an experiment, and discuss how experimental control contributes to causal explanation. Describe the three measures of central tendency and the two measures of variation. Explain why psychologists study animals, and discuss the ethics of experimentation with both animals and humans.

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.

Chapter 14 Mendel and the Gene Idea Lecture Outline Overview: Drawing from the Deck of Genes The ?blending? hypothesis popular 1800s This hypothesis proposes that genetic material contributed by each parent mixes in a manner analogous to the way blue and yellow paints blend to make green. With blending inheritance, a freely mating population will eventually give rise to a uniform population of individuals. Everyday observations and the results of breeding experiments tell us that heritable traits do not blend to become uniform. An alternative model: the ?particulate? inheritance proposes that parents pass on discrete heritable units, genes, that retain their separate identities in offspring. Genes can be sorted and passed on, generation after generation, in undiluted form.

Chapter 13 Meiosis and Sexual Life Cycles Lecture Outline Overview: Hereditary Similarity and Variation Living organisms are distinguished by their ability to reproduce their own kind. heredity or inheritance. The transmission of traits from one generation to the next is called offspring differ somewhat from parents and siblings, demonstrating variation. Farmers have bred plants and animals for desired traits for thousands of years, but the mechanisms of heredity and variation eluded biologists until the development of genetics in the 20th century. Genetics the scientific study of heredity and variation. Concept 13.1 Offspring acquire genes from parents by inheriting chromosomes Genes are segments of DNA.
