DNA Building Blocks

thingiverse

This model depicts the structure of DNA and its building blocks. Adenine and Thymine blocks connect only to themselves, as do Guanine and Cytosine blocks. Sugar and phosphate blocks, represented by S and P letters respectively, attach to base pairs without restriction on orientation. Once a segment is complete, it can be connected to another to form a longer DNA strand. The goal of this project was to educate students about how DNA connects its components. It also demonstrates the ability to create different combinations through this process. This model is suitable for any grade level or skill set, making it perfect for a Biology or Genetics class. No prior knowledge or resources are required to use this project; however, understanding what DNA is and its role in the human body can be beneficial but not necessary. The objective of this project is to visualize how DNA forms through the connection between Nitrogenous bases Adenine and Thymine, which only connect to each other, and Guanine and Cytosine, which also only connect to themselves. Additionally, sugars and phosphates can connect to any base or sugar. Upon completion, students should be able to identify the components of DNA and how they interact with one another. They should also understand that different combinations of these base pairs create a unique code for an organism. An assignment could involve creating a DNA strand for students to recreate and grading based on accuracy.
