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.

Anatomy and Physiology is a dynamic textbook for the two-semester human anatomy and physiology course for life science and allied health majors. The book is organized by body system and covers standard scope and sequence requirements. Its lucid text, strategically constructed art, career features, and links to external learning tools address the critical teaching and learning challenges in the course. The web-based version of Anatomy and Physiology also features links to surgical videos, histology, and interactive diagrams.

DNA is composed of two strands of nucleotides held together by hydrogen bonding. The strands each run from 5' to 3' and run in antiparallel, or opposite, directions from one another.

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:

"It’s a feared moment for every scientist: the discovery that years of painstaking research has led to results that can't be repeated. Many think that poorly characterized antibodies have contributed to this reproducibility crisis more than any other laboratory tool. A new study published in Molecular Cell supports this hypothesis, at least in the context of chromatin immunoprecipitation. Although accurate ChIP interpretation depends on near-perfect antibody specificity, the report shows that many of these reagents are far less capable than their advertising suggests, which calls into question several widely accepted paradigms on genomic regulation. The study focused on histone post-translational modifications; specifically all three methylation states of lysine 4 on histone H3. Through ChIP experiments, H3K4 methylation has been strongly linked to transcriptional control..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

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.

Students act as if they are biological engineers following the steps of the engineering design process to design and create protein models to replace the defective proteins in a child’s body. Jumping off from a basic understanding of DNA and its transcription and translation processes, students learn about the many different proteins types and what happens if protein mutations occur. Then they focus on structural, transport and defense proteins during three challenges posed by the R&D; bio-engineering hypothetical scenario. Using common classroom supplies such as paper, tape and craft sticks, student pairs design, sketch, build, test and improve their own protein models to meet specific functional requirements: to strengthen bones (collagen), to capture oxygen molecules (hemoglobin) and to capture bacteria (antibody). By designing and testing physical models to accomplish certain functional requirements, students come to understand the relationship between protein structure and function. They graph and analyze the class data, then share and compare results across all teams to determine which models were the most successful. Includes a quiz, three worksheets and a reference sheet.

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.
