Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

This resource provides a fillable form pdf laboratory procedure and answer sheet for an online mitosis laboratory. It utilizes the a virtual onion root tip activity developed by D.K. Warren at The University of Arizona (http://www.biology.arizona.edu/cell_bio/activities/cell_cycle/cell_cycle.html). It was designed for use as a somatic cell division laboratory exercise in an introductory online biology course.

The lab utilizes a fillable form pdf lab answer sheet created by the instructor, Tina B. Jones.

Attributions and references are provided at the end of the laboratory write-up.

Please refer to the "Completing Lab Reports in Canvas Orientation Exercise" in OER Commons, also authored by Tina B. Jones, for student instructions on downloading, completing, and uploading the fillable form answer sheets in Canvas.

*Lab answer sheet created by instructor using Adobe Acrobat DC Pro.

By the end of this section, you will be able to:Describe the structure of prokaryotic and eukaryotic genomesDistinguish between chromosomes, genes, and traitsDescribe the mechanisms of chromosome compaction

All living beings are made up of cells. Some of them are made up of only one cell and others have many cells. Also in: Dutch | French | Hungarian | Spanish

This is information to be used for a General Biology I (or Introduction to Biology) course for non-science majors.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Fibroblast growth factors (FGFs) allow cells to receive signals from the outside world by binding to and activating FGF receptors (FGFRs). The resulting signaling cascades help regulate important processes such as proliferation, motility, metabolism, and death. Dysregulation of these signaling cascades can result in developmental disorders, metabolic diseases and cancer. Although much is known about how FGFs work, the function of the fibroblast homologous factor (FHF) subfamily of FGFs has been unclear. Researchers have now shown that FHF1 exhibits some similarities to other FGFs. They found that FHF1 binds all major FGFRs. Upon binding, FHF1 can activate FGFR1 and initiate receptor-dependent signaling cascades. protecting cells from death. However, unlike other FGFs, it is not capable of stimulating cell division. These results identify FHF1 as a new FGFR ligand that should be considered when studying diseases with overactive FGFRs..."

Students are given a problem about a relatively new treatment for cancer, Gleevec, and asked to apply and synthesize what they have learned about cell signaling and the eukaryotic cell cycle to explain why this targeted treatment works to prevent cell division with fewer side effects than traditional chemotherapeutic agents.

Help Me Understand Genetics presents basic information about genetics in clear language and provides links to online resources.

Welcome! This is the site for the lecture component of Bio1100 D854. This site contains the lecture syllabus and links to the free OER (open educational resource) textbooks that we will be using.

The Genetics Student Edition book is one of ten volumes making up the Human Biology curriculum, an interdisciplinary and inquiry-based approach to the study of life science.

The Lives of Cells Student Edition book is one of ten volumes making up the Human Biology curriculum, an interdisciplinary and inquiry-based approach to the study of life science.

At the beginning of a DNA, DNA replication, and mitosis unit, students are given a short science news article summarizing a recent research paper. This assignment links the article to figures and key techniques from a related journal article, requiring students to apply and transfer the knowledge they gained in the unit.

Life is unique because of diversity. Take a look at a room full of children; no two will be alike.  What is the mechanism at the cellular level that causes this? Meiosis is the process of cell division that facilitates this process. During meiosis, special cells form for the purpose of reproduction.    In this seminar, you will learn how meiosis creates gametes with half the number of chromosomes of the parent cell, and you will explore the steps in cell division. The process of mitosis and meiosis are very similar, and you will need to reflect and differentiate between the two.   Additionally, you will be challenged to create physical models of the process while applying new understanding.  StandardsBIO.B.1.1.2 Compare and contrast the processes and outcomes of mitotic and meiotic nuclear divisions.

Meiosis is the process by which gametes (eggs and sperm) are made. Gametes have only one set of chromosomes. Therefore, meiosis involves a reduction in the amount of genetic material. Each gamete has only half the chromosomes of the original germ cell. Explore meiosis with a computer model of dragons. Run meiosis, inspect the chromosomes, then choose gametes to fertilize. Predict the results of the dragon offspring and try to make a dragon without legs. Learn why all siblings do not look alike.

Welcome to the Teachers' Corner of Small Things Considered. In this section, we include the posts we deem most adequate for teaching purposes. We have reorganized them into subject areas geared for a typical microbiology course. To date, this material has been used for various forms of intellectual enrichment, e.g., suggested readings, class presentations, a source of topics for term papers. You can also find here our Talmudic Questions, which we characterize as those whose answers cannot be found in Google. We are told that some of these questions have been used in exams ranging from tests for undergraduate courses to qualifying/prelims for graduate students.

"An international team of biologists has done the seemingly impossible. They’ve revived cell nuclei from a 28,000-year-old frozen woolly mammoth. While the world will have to wait for the first full-blown mammoth resurrection, this could be a big step in that direction. The team’s findings offer researchers hope that ancient DNA, though damaged, could one day be made functional. The research team salvaged the nuclei from the muscle of “Yuka,” a young woolly mammoth well preserved in Siberian permafrost since the last ice age. They then transplanted them into mouse egg cells. This process, called somatic cell nuclear transfer, is the same one used to clone animals like Dolly the sheep. But unlike for Dolly, the development of those nuclei stopped short of cell division. After the transfer, researchers observed filling of the transplanted nuclei with mouse proteins—namely, histone and tubulin— and the formation of a new nucleus-like structure..."

For this unit plan, see the old unit calendar (link on left sidebar, click ALT3 tab at the bottom).  Once we update this unit to the new Doc template, we will post it here. This is now unit 3, but it used to be unit 2 (we will update file and folder numbering as we continue to revise the units). Thanks for your patience as we work hard this year to update all of the materials to the new unit template and unit/standards arrangements.
