DNA is deoxyribonucleic acid. It contains the genetic instructions used in the functioning and development of all living orgainisms and some viruse.Bored with your project on DNA? Just realized that it's due tomorrow? Well keep reading, even if you don't have to create an accurate model of DNA! It's really fun, and there's always leftover candy.
Gummy Bears (at least four colors)
Red Licorice (cut into 1 inch pieces)
Black Licorice (cut into 1 inch pieces)
Markers, pens, etc.
Glue or Tape
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.
