In this project, each student will be assigned to a group of three to four students. Each group will be given random character description cards. These characters will be treated as the first generation in a fictitious town. The cards will include specific genetic traits, skills, jobs, as well as reference if the character suffers from type 2 diabetes. Students will need to use the character cards to author and illustrate a short story about the fictitious town which follows at least three generations of the families in the cards. Students must also include pedigrees for a minimum of three traits as well as diabetes as evidence of inheritance.

"Normally, an animal gets half its DNA from its mother and half from its father. But Dolly had three mothers: one mother gave Dolly her DNA; one supplied an egg; and the third, her surrogate mother, gave birth to her. Dolly is an identical twin of the mother who gave her her DNA. But Dolly is six years younger."This kid-friendly Web page helps kids understand how and why Dolly was cloned, and understand the potential benefits of cloning as well as the controversy it raises.
This research profile follows Dr. Rosemary Gillespie to Hawaii as she evaluates hypotheses about the evolution of the colorful happy-face spider.
This class analyzes complex biological processes from the molecular, cellular, extracellular, and organ levels of hierarchy. Emphasis is placed on the basic biochemical and biophysical principles that govern these processes. Examples of processes to be studied include chemotaxis, the fixation of nitrogen into organic biological molecules, growth factor and hormone mediated signaling cascades, and signaling cascades leading to cell death in response to DNA damage. In each case, the availability of a resource, or the presence of a stimulus, results in some biochemical pathways being turned on while others are turned off. The course examines the dynamic aspects of these processes and details how biochemical mechanistic themes impinge on molecular/cellular/tissue/organ-level functions. Chemical and quantitative views of the interplay of multiple pathways as biological networks are emphasized. Student work will culminate in the preparation of a unique grant application in an area of biological networks.
In this anatomy version of jeopardy, you will be quizzed on the following topics: biomolecules, lipids, carbohydrates, DNA and RNA, and proteins. Good Luck!
This fun Web site is part of OLogy, where kids can collect virtual trading cards and create projects with them. Here, they take a look at genetics and DNA research with six AMNH scientists' journals. The Humpback Whale Journal takes kids to Madagascar to meet this endangered species. The Spotted Owl Journal takes kids to California for a look at these birds who are at risk because their forest homes are being cut down. The Sumatran Tiger Journal takes kids to Indonesia for a look at this genetically unique tiger. The Ruffed Lemur Journal also takes kids to Madagascar, but this time they venture inland to meet the endangered primate. The Pacu Journal takes kids to Brazil to meet this vegetarian relative of the meat-eating piranha. The St. Vincent Parrot Journal takes kids to the West Indies to meet the rare, colorful birds that are further at risk because of smuggling.
Students construct paper recombinant plasmids to simulate the methods genetic engineers use to create modified bacteria. They learn what role enzymes, DNA and genes play in the modification of organisms. For the particular model they work on, they isolate a mammal insulin gene and combine it with a bacteria's gene sequence (plasmid DNA) for production of the protein insulin.
Becoming Human is an interactive documentary experience that tells the story of human origins. Multimedia, research and scholarship are presented to promote greater understanding of the course of human evolution. This site includes classroom materials, subject-designed exercises, games and activities to help make connections between the concepts that are presented and student learning. PDF versions of the resources may be downloaded from the site.
" The course, which spans two thirds of a semester, provides students with a research-inspired laboratory experience that introduces standard biochemical techniques in the context of investigating a current and exciting research topic, acquired resistance to the cancer drug Gleevec. Techniques include protein expression, purification, and gel analysis, PCR, site-directed mutagenesis, kinase activity assays, and protein structure viewing. This class is part of the new laboratory curriculum in the MIT Department of Chemistry. Undergraduate Research-Inspired Experimental Chemistry Alternatives (URIECA) introduces students to cutting edge research topics in a modular format. Acknowledgments Development of this course was funded through an HHMI Professors grant to Professor Catherine L. Drennan."
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.
