Paul Andersen explains how the Meselson-Stahl experiment was used to prove that DNA copied itself through a semi-conservative process. They grew E. coli in a medium containing heavy nitrogen (N-15). They then added the E. coli to a medium containing regular nitrogen (N-14) and observed it over several generation.

Students explore the relationships between genetics, biodiversity, and evolution through a simple activity involving hypothetical wild mouse populations. First, students toss coins to determine what traits a set of mouse parents possesses, such as fur color, body size, heat tolerance, and running speed. Next they use coin tossing to determine the traits a mouse pup born to these parents possesses. These physical features are then compared to features that would be most adaptive in several different environmental conditions. Finally, students consider what would happen to the mouse offspring if those environmental conditions were to change: which mice would be most likely to survive and produce the next generation?

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

As a group of organisms that are too small to see and best known for being agents of disease and death, microbes are not always appreciated for the numerous supportive and positive contributions they make to the living world. Designed to support a course in microbiology, Microbiology: A Laboratory Experience permits a glimpse into both the good and the bad in the microscopic world. The laboratory experiences are designed to engage and support student interest in microbiology as a topic, field of study, and career. This text provides a series of laboratory exercises compatible with a one-semester undergraduate microbiology or bacteriology course with a three- or four-hour lab period that meets once or twice a week. The design of the lab manual conforms to the American Society for Microbiology curriculum guidelines and takes a ground-up approach -- beginning with an introduction to biosafety and containment practices and how to work with biological hazards. From there the course moves to basic but essential microscopy skills, aseptic technique and culture methods, and builds to include more advanced lab techniques. The exercises incorporate a semester-long investigative laboratory project designed to promote the sense of discovery and encourage student engagement. The curriculum is rigorous but manageable for a single semester and incorporates best practices in biology education.

This on-line open source BIOL& 260 (Microbiology) is a health sciences oriented course in microbiology. It has a laboratory component and the labs are intended to be integrated throughout the course. BIOL& 260 is intended primarily for students going in to health-related professions and will emphasize the human disease and health related areas of microbiology. Areas of microbiology such as environmental, agricultural, taxonomy or astrobiology may be mentioned but not emphasized.

Microbiology for Allied Health Students is designed to cover the scope and sequence requirements for the single semester Microbiology course for non-majors and allied health students. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of Microbiology for Allied Health Students make the material interesting and accessible to students while maintaining the career-application focus and scientific rigor inherent in the subject matter.

The scope and sequence of Microbiology for Allied Health Students has been developed and vetted with input from numerous instructors at institutions across the U.S. It is designed to meet the needs of most microbiology courses allied health students.

With these objectives in mind, the content of this textbook has been arranged in a logical progression from fundamental to more advanced concepts. The opening chapters present an overview of the discipline, with individual chapters focusing on cellular biology as well as each of the different types of microorganisms and the various means by which we can control and combat microbial growth. The focus turns to microbial pathogenicity, emphasizing how interactions between microbes and the human immune system contribute to human health and disease. The last several chapters of the text provide a survey of medical microbiology, presenting the characteristics of microbial diseases organized by body system.

Paul Andersen defines microevolution as any change in the frequency of the allele pool. He then explains the five mechanisms of evolution; small sample size, non-random mating, mutations, gene flow and natural selection.

Paul Andersen describes the process of mitosis. He begins by discussing the importance of the cell cycle in development, regeneration, asexual reproduction and wound healing. He differentiates between haploid and diploid cells and describes the structure of the chromosome. He then moves through all the phases of mitosis; interphase, prophase, metaphase, anaphase, telophase and cytokinesis.

This "Mitosis" learning object is the from the Sumanas resource series. Sumanas offers a robust selection of content and services that are directed at enhancing the learning experience.

Paul Andersen compares and contrasts mitosis and meiosis. He shows how you can count cells in various phases of mitosis to construct a cell cycle pie chart. He also explains how you can use the fungus Sordaria to calculate map units using the frequency of cross over.

Hank describes mitosis and cytokinesis - the series of processes our cells go through to divide into two identical copies.

The video resource "Mitosis: Splitting Up is Complicated - Crash Course Biology #12" is included in the "Biology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.

In this video Paul Andersen explains the importance of models and visual representations in an AP Biology class. Science practices are overarching skills and knowledge required to be successful in an AP Biology classroom. Models for each of the four big science ideas are included.

Paul Andersen explains the major procedures in molecular biology. He starts with a brief description of Taq polymerase extracted from the hot pools of Yellowstone Park. He then uses the analogy of the ransom note to explain each of the processes that are required in genetic engineering.

Paul Andersen explains the two major portions of the molecular biology lab in AP Biology. He starts by discussing the process of transformation. He explains how you can use the pGLO plasmid to produce glowing E. coli bacteria. He then describes how you can use restriction enzymes and the process of gel electrophoresis to cut and separate DNA.

Paul Andersen describes the macromolecules that make up living organisms. He starts with a brief description of organic chemistry and the importance of functional groups. He also covers both dehydration and hydrolysis in polymerization. He finally covers the four major macromolecules: nucleic acids, proteins, lipids and carbohydrates.
