The purpose of this case is to teach introductory college biology students the basic process of mitosis, focusing on the fundamental cellular processes that occur during each of the stages-prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis. It would also be appropriate for AP Biology students. The case is framed around solving a murder. The murder plot involves a naturally-occurring poison derived from Yew trees, known as paclitaxel. Paclitaxel is a mitotic inhibitor that works by inhibiting the depolymerization of microtubules so that the cell is arrested in metaphase. At the end of the case, students will be able to describe the basic process of mitosis, including the fundamental processes that occur in each stage. The discovery of paclitaxel led to the development of the chemotherapeutic drug, Taxol ®, and the case concludes by having students think about the correlations between poisons and chemotherapies. The case involves the use of videos, one of which was made by the author for this case, and can be used in a flipped classroom.

Studying odors from corpses may sound macabre, but it's actually a virtuous vocation. Researchers in this field are helping find missing bodies lost in natural disasters or hidden by murderers. ↓↓More info and references below↓↓

There are a significant number of genetics curriculum resources designed by different companies, curriculum development outlets, state curriculum designers and individual teachers. What resources are good? How do you know? As part of the Geneticist-Educator Network of Alliances (GENA) Project, a Curriculum Content Review Committee was formed to review readily available classroom resources about patterns of inheritance.

This case study presents the mock trial of "Martin Miller." There is no question that Martin killed his girlfriend; he admitted to stabbing her in a violent rage. But what is the degree of his responsibility? By virtue of Martin having the MAOA-L gene variant, together with a history of childhood abuse, should his punishment be reduced? This hypothetical case, which requires students to think through the issues rather than simply look up a verdict, is based on actual events and violent behaviors that resulted in criminal charges claimed to be related to MAOA. The MAOA gene and its effect on behavior have been extensively studied, and research results have been introduced as evidence in court cases with differing results. The present case study allows students to explore how behavioral genetic information can be applied to a courtroom situation, and requires them to integrate information from biology, ethics, and the law. Note: Due to the unusual structure of the case, no answer key is available.
