The science behind each concept is explained using animations related to DNA topics, an image gallery, video interviews, problems, biographies, and links related to DNA. There are three sections, Classical Genetics, Molecules of Genetics and Organization of Genetic Material. Key features are the clear explanations of classical experiments and the excellent photographs of researchers and their labs.For information and credits on the development of DNA from the Beginning, go to http://www.dnaftb.org/dnaftb/credits.html http://www.merlot.org/merlot/viewMaterial.htm?id=83572 Students play the role of predators on moths on a tree trunk. Then, they play the role of biologist, analyzing the changing gene frequencies of the moth population and determining if the population evolved over three generations. Students will: 1) collect data by eating moths; 2) calculate gene frequencies for each phenotype over three generations; 3) interpret graphs of data their data to determine if microevolution occurred; and 4) explain how selection acts on populations.To view a video of the award winning author, go to View Connecting Concepts - Biology Award Winner 2008 video The authors also participated in the MERLOT Classics Series on Elluminate: " target=״_blank״>https://sas.elluminate.com/site/external/jwsdetect/playback.jnlp?psid=2010-03-31.1707.M.9E9FE58134BE68C3B413F24B3586CF.vcr http://www.merlot.org/merlot/viewMaterial.htm?id=91119 Protein Explorer provides a user interface to the Chime plugin allowing easy manipulation and viewing of PDB structure files. Includes most RasMol commands and has a command line, but has buttons and menus for many useful commands. Includes a comparator funciton that allows comparisons between two structures, molecules in the structure can be selected in a sequence window and there is a non-covalent bond finder function. http://www.merlot.org/merlot/viewMaterial.htm?id=91398 This site provides information about cell components (such as cell wall, cell membrane, nucleus, endoplasmic reticulum, Golgi apparatus, cytoskeleton, cytosol, mitochondrion, chloroplast, peroxisome, lysosome, vacuole, etc.) and cell division (meiosis, and mitosis), as well as beautiful images in cell biology. Video and still pictures of various types of eukaryotic and prokaryotic cells are included. A great animation on how bacteria grow and divide is an added plus for this site. http://www.merlot.org/merlot/viewMaterial.htm?id=90953 As descibed at the site, "The Tree of Life is a project containing information about the diversity of organisms on Earth, their history, and characteristics. The information is linked together in the form of the evolutionary tree that connects all organisms to each other." http://www.merlot.org/merlot/viewMaterial.htm?id=81028 People have misconceptions about evolution. Some are simple misunderstandings; ideas that develop in the course of learning about evolution, possibly from school experiences and/or from the media. Other misconceptions may stem from purposeful attempts to interfere with the teaching of evolution. Science teachers must learn to treat all student questions with respect and initially to accept each question as the reflection of a legitimate desire to learn. However, some questions may well be designed to disrupt the learning process. We need to deal with intentionally disruptive questions in ways that are a bit different from legitimate inquiry. And it is important that we learn to distinguish between the two. This web site explains how to teach evolution in the classroom, with concepts, lesson plans and teaching philosophy about teaching evolution. It also provides a glossary and a guide to identifying and dealing with potential obstacles to the teaching of evolution and provides links to readings, websites, and position statements. The site was created by the University of California Museum of Paleontology with support provided by the National Science Foundation and the Howard Hughes Medical Institute. http://www.merlot.org/merlot/viewMaterial.htm?id=87805 A large collection of small java simulations that illustrate various aspects of evolution. Topics covered include statistics, selection, mutation, gene flow, genetics, reproduction, genetic drift, adaptation, speciation, extinction, phylogenetics and sexual selection. http://www.merlot.org/merlot/viewMaterial.htm?id=89970 A lecture aid for use in the classroom, to provide figures, and for student exploration. Provides interactive 3-dimensional images of proteins and nucleic acids. Has examples in both the newer Jmol and the older Chime formats. http://www.merlot.org/merlot/viewMaterial.htm?id=90955 Eight tutorials or problem-based assignments covering the topics of polio, BSE (mad cow disease), antibiotics, the eradication of smallpox, yellow fever, complement, virus replication, and a history of viruses. http://www.merlot.org/merlot/viewMaterial.htm?id=91370 A collection of on line labs for introductory Zoology or Animal Biology. Mostly annotated images some at different levels of magnification.
