We're going to teach you how to make a DNA model out of sweets. This is going to be the sugar phosphate backbone. We have our toothpick which is going to be our bond. And lastly, we have a beautiful selection of tasty sweets which are actually going to be our nucleotides. We have adenine, thymine, guanine, and cytosine. Now, if you could all brace yourselves and get your protective goggles on, we're going to make this delicious DNA model. Take one of your bonds here, place an adenine all the way through the toothpick, pick up your thymine and, the important part, is bonding this together to the sugar-phosphate backbone. And what you want to do is follow this all the way down as if you were going down a ladder. Don't forget that adenine always goes with thymine and guanine with cytosine. And if you twist it like so, you have your double helix structure, and it tastes really good, too. .
