What Is The 3D Structure Of DNA?
DNA looks like a twisted ladder called a double helix. The sides of this ladder are made of sugar and phosphate parts. The steps, or rungs, are made of four bases: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). These bases always pair in a specific way: A with T and G with C. They stick together with hydrogen bonds. The helix twists once every ten pairs of bases. It is 2 nanometers wide, and each base pair is 0.34 nanometers apart. This shape helps DNA store genetic information and copy itself correctly when cells divide.

How To Make a DNA Model With Paper?
Materials Needed
You will need two different colors of regular paper for the DNA strands. You also need scissors, glue or tape, and a ruler. If you want a stronger model, you can use cardstock instead of regular paper.
Step 1: Create the Backbones
Cut two long strips of paper. Each strip should be about 2 inches wide and 11 inches long. Make a line down the middle of each strip. Then, mark every 2 inches where you will place the base pairs.
Step 2: Make the Base Pairs
Cut four shorter strips of paper about 1 inch wide and 3 inches long. These are your base pairs (A-T and G-C). If you want to be accurate, label them: A pairs with T, and G pairs with C.
Step 3: Assembly
Glue or tape the base pairs between the two backbone strips at the marks you made. Make sure to switch sides as you attach them to create the ladder shape.
Step 4: Final Twisting
Gently twist the whole structure to form the double helix shape. Be careful not to tear the paper. Your model should look like a spiral staircase with the base pairs as the steps.
Tips for Success
Make sure your folds are neat, and don’t rush when gluing. Let each connection dry well. If your model feels weak, add more tape or use thicker paper to make it stronger.

Summary
DNA model project ideas for students can make learning about science fun and easy. All these projects help students see and understand the special shape of DNA.
By building these models, students learn how the four parts (adenine, thymine, cytosine, and guanine) fit together and how the sugar-phosphate backbone keeps it all connected.
Thus, making DNA models helps students understand genetics better, makes learning more fun, and helps them be creative problem-solvers.
