Description
Constructing a DNA double-helix self-twisting paper model is an engaging process using the provided kit. The kit comprises templates for the DNA nucleotides A, T, G, and C, available in both colored and black & white versions, and in two different sizes. Rectangles represent the nitrogen bases, circles represent phosphate groups, and pentagons represent the deoxyribose sugar.
To assemble the model, follow these steps:
Construction paper, 110 g, is better to be used for this model.
1.Choose the desired size and color for the templates, then cut them out.
2.B&W template can be colored before cutting by any coloring medium should you wish.
3.The small size templates can make together a reasonable length molecule, but for the big ones, several copies should be printed depending on the final desired length of the molecule.
4.Photos for the assembly process are available in the kit.
5.Apply glue to the two small rectangles on the side of either of the letters (A, T).
6. Connect each pair so the rectangles are on top of each other, ensuring one nucleotide is upright while the other is flipped upside down. The orientation of the letters indicates the direction of the nucleotide.
7.Do the same for the pair (C,G). This time three rectangles should be glued for either unit.
8.Arrange the pairs in a sequence, alternating between A on the left and T, and similarly for G and C.
9.Join the phosphate group to the sugar molecule using the small rectangle on each side of the nucleotide pair. Ensure proper alignment, forming a straight line. The rectangle protruding from the sugar molecule should touch the circle representing the phosphate group. This connection will link one pair to another, initiating a twist.
10.Continue this process until you have assembled at least ten pairs stacked above each other.
11.The cumulative effect should reveal a complete circular structure when viewed from the top.
This model can be used to teach the structure of the nucleotide, base-pairing rule, anti-parallel strands, double helix meaning, the sugar-phosphate back bone, and can even be cut to simulate the process of DNA replication.
Enjoy the creative and educational experience of constructing your DNA double-helix model!

Thank you for sharing this. Yes, this is why there are two versions. You can also ask them to do the cutting and coloring at home before the class, one pair of bases for each student, then do the assembly in the class.
