Step 1: Make a Key

First, you will need to know what is what on your DNA model. Write "Key" on the top of your poster board/paper. Then, glue or tape on a piece of black licorice. Label it "phosphate groups". Attatch a piece of red licorice and label it "sugar deoxyribose". These two make up the sugar-phosphate backbone of DNA. Take one gummy bear and attatch it to the paper. Label it "adenine". Then, take a different color bear, attatch it, and label it "thymine". Attatch another color and label it guanine, and then attatch another color labeled "cytosine". These are DNA's four bases. Attatch a marshmallow and label it "hydrogen bonds that connect the bases". If you want some extra credit, try adding these facts:

The order of the bases determines the type of organism and its functionality.

DNA's shape is a right-handed double helix.
THNX FOR THE INFO. BUT PEALSE CAN U PUT A PICTURE OF IT WHILE IT IS TWISTED BECAUSE I AM REALLY CURIOUS TO SEE IT
I made this a LONG time ago, so I don't have one. It won't stay twisted...sorry. It looks pretty much like you would think it look. If you want, you can look up a picture of a double helix.
CAN U SHOW US THE CANDY DNA MODEL WHILE IT IS TWISTED PLEASE
You could use a chopstick to make it a double helix<br />
The &quot;bases&quot; and &quot;hydrogen bonds&quot; are on toothpicks connected to alternating colors of licorice that are the &quot;sugar deoxyribose&quot; and &quot;phosphate groups&quot;. Then, you twist it so that it forms a double-helix.
I'm sure this is great, but I can't see it. Have you got a nice picture of the double-helix? L
Here you go! Sorry it isn't twisted.
Ah yes I see it now, thanks L
