DNA Structure & Testing : How to Make a DNA Model

Making a DNA model, which is in the form of a double helix, requires using four colors to represent adenine, guanine, cytosine and thymine, the four bases that make up the genetic material. Make a DNA model to better understand it withinformation from a biology teacher in this free video on science.

   Thanks for not helping. Next time tell us something we don’t know. Such as what the materials for making the model is.

    Good info. To make an actual model at home, it doesn’t work to make the ladder first and then twist it because it won’t twist evenly and it also twists and distorts the base pairs which are supposed to be straight across from the sugar molecule of one outer strand to the sugar molecule of the opposite strand. It’s best to make the outer framework first by wrapping wire around a cylinder-shaped object, next create the double helix, and lastly connect base pairs to stabilize it.

    Thank-you for the info!
    How did you make the DNA model you are using as an example?
