Double Helix Science Club is named after the famous shape of DNA. Learn about DNA and its role in life, then make your own DNA model.Deoxyribonucleic acid DNA is a molecule that contains all the information to determine who you are and what you look like.
Let’s work from the large to the small.
Your body is made up of many different chemicals. An important group of chemicals is the proteins, which build your body and help it to function
Each protein is formed from over 100 amino acids. There are 20 different types of amino acids that can be used to make proteins
Print out the templates of the DNA rungs and spines (stiff card works better then regular paper). You’ll find the link to the DNA model template to the right of this page.
Photocopy or paste the templates onto light cardboard. The ideal dimensions for the model are printed on the template, so you may need to enlarge or reduce the model..
Cut out spines A and B..
Cut out the rungs..
Fold down the tabs so that they are at right angles to the rungs (as shown in the picture)..
Put glue on one tab of each rung and stick them onto spine A in the numbered boxes. You can attach the rungs in any order (pointing either way). Wait for the glue to set before proceeding. You may also want to hold the rung on with a paper clip or clothes peg so it sticks well..
Once the glue is dry, put glue on the other tab of each rung and stick them to the corresponding numbered position on spine B. This is the tricky part because you’ll have to support both spines while the glue is drying. Once again, this is where pegs will be a BIG help..
When you’ve completed your model, hang it from the ceiling. To complete the presentation of your molecule, cut out the Double Helix label that appears with the rungs and hang it from the bottom of the double helix..
