A 3D DNA model will enable kids to understand the concept of DNA in a fun and interesting way. Be it for a school project or just an activity to study DNA better, making a model can be fun and exciting too! And yes, simple materials are all you need, to make this model. Before we begin with the different ways in which you can make a DNA model, it is crucial to understand the basic structure of DNA. DNA, or deoxyribonucleic acid, is like the building blocks of human life. They are present in all humans and most other organisms. James Watson and Francis Crick first figured out the structure of DNA is a double-helix. The structure is fairly simple, resembling a twisted ladder. To make a 3D model, we need to make two strands―sugar and phosphate―and then pairs of nitrogenous bases―adenine and thymine and cytosine and guanine. Just attach the bases like steps of a ladder between the two strands, twist them, and your DNA model is ready! Remember DNA always twists to the right. The four bases are adenine, thymine, cytosine, and guanine. Adenine and thymine, and cytosine and guanine are always paired together. Here, we have provided an easy step-by-step guide to create a 3D DNA model using only clay.

• Polymer clay (six colors)
• Flexible wire
• Oven

Here, we will use polymer clay as it can be baked. Normal clay model will not be sturdy enough, especially if you want a larger model for projects or exhibitions. You need polymer clay in six different colors, one color each for sugars, phosphates, adenine, thymine, cytosine, and guanine. Flexible wires will help support your model better. That was easy, wasn't it? You can also use beads or small balls to make the nitrogenous bases, and use toothpicks to attach them. Making a model will help you understand the structure of DNA instantly. Have fun!
