Description

       This course introduces students to the scientific and intellectual journey that led to our current understanding of DNA, blending historical context, interdisciplinary discovery, and modern biophysical tools. Anchored in the story of the DNA double helix, the course explores how researchers—from Darwin and Mendel to Franklin, Watson, and Crick—unraveled the mysteries of heredity and molecular structure.
       The course emphasizes interdisciplinary learning through hands-on activities. Students will examine how pivotal experiments shaped our understanding of DNA and genetic material, while visualizing macromolecular structures using computational tools, interpreting classic experiments such as DNA diffraction patterns, and analyzing scientific images, including fluorescence microscopy. To broaden their exposure to scientific research, students will also attend seminars and engage with guest scientists.
       Throughout the course, students will develop core academic skills such as reading and interpreting scientific texts, scientific writing through article analysis and reflection, literature mining, and presenting scientific ideas—all within the context of key concepts in genetics, structural biology, and biophysics.
       No prior STEM experience is required. Students will be introduced to the culture of scientific inquiry and to the broader university environment, including how to navigate and make use of the university’s extensive academic resources. This course is ideal for students curious about how science shapes our understanding of life, and eager to build foundational college-level skills through the lens of a transformative scientific discovery.

Reading and Materials

Multiple resources—including research papers, textbooks, and online materials—are provided during lectures and made available on the course site (Files/Materials Folder). Below are some of the key textbooks used in preparing lecture content. 

•    Lodish et al., Molecular Cell Biology

•   Encyclopedia of Cell Biology (UM library)

•  James Watson and Andrew Berry, DNA: The Secret of Life

•  The Gene: An Intimate History by  Siddhartha Mukherjee - available on UM library - can't be downloaded

If you have any questions, you can also ask Maizey, the AI tutor trained on the class materials.

Use of ChatGPT and other AI Tools

It’s your responsibility to assess every source’s reliability. AI tools like ChatGPT are a source that may inform your writing, just as books, papers, lecture notes, websites, and the results of Google searches. You should be aware that the output of AI tools is not checked by an expert.

AI tools can generate text, code, and images in response to a prompt. Such automatically generated text is not your work and cannot be submitted as if it is.  Exceptions are assignments that specifically ask for the use of AI.
