How to make your candy DNA model

Genes are a set of instructions held on a string of DNA, which tells a cell how to make a specific protein or enzyme molecule. This special set of instructions is made up of individual pairs of nucleotides.

image00029These 4 nucleotides, along with the sugars and phosphates, make up your double helix candy DNA model: Adenine, Thymine, Cytosine, Guanine. So, before you start making your model, assign a colour to each of the 4 nucleotide within your codon, remember C and G and T and A always pair up.

Create your nucleotide pair by inserting the candy onto the cocktail sticks.
-remember to be careful of the pointy ends on the cocktails sticks!
Make sure your grown up is here for this part.

Attach each end of the cocktail stick to your strawberry pencil,
evenly spacing each stick until you’ve made a long enough string.

Once you’ve done that, give a slight twist to create the classic twisty helix!
