3D Printed Molecules

This is a 3D model of BRCA2 and Rad51 molecules, which are two proteins used in DNA repair, crucial to discovering how we can cure breast cancer and ovarian cancer. These models are valuable for teaching all students, but especially helpful in introducing a complicated topic like biology to visually impaired students. The models feature magnets that explain exactly where and how these two molecules bind together, offering a tangible way to teach all students, particularly visual learners and those with visual impairments. Initially sourced from the Protein Data Bank, these models were modified to show how BRCA2 mediates Rad51 in homologous recombination. With this teaching tool, you can explain what a molecule or protein is, what amino acids and polypeptide chains are, what bonds are, and explain DNA repair and homologous recombination. This project features two models: one of a Rad51 with a BRC repeat, and multiple Rad51 molecules bonded together to form a Rad51 filament. These proteins are involved in homologous recombination, a type of DNA repair, and offer immense help in teaching this complex area of the sciences. I studied these proteins in my biology class, and spent several months researching this topic, so anyone looking for a more in-depth explanation of the role of these two molecules to use as a lesson plan or out of curiosity can reach out to me.
