A lab activity for students to determine the structure of dna and understand how the genetic code is carried. Students will color-code nucleotides and join them together to form a model of dna. Questions about the common and differing parts of nucleotides, the pairing arrangement of nitrogen bases, and the sequence of bases in the dna molecule.

Name ______________________ Discovering DNA Structure Section _____________________
DNA contains the information for carrying out the activities of the cell. How this information is coded or passed from cell to cell was at one time unknown. To break the code, today you will do a paper lab to determine the structure of DNA and show how the genetic code is carried. Each member of your group has a molecule called a NUCLEOTIDE. DNA is made up of repeating units of nucleotides.
Color the nucleotides using the following key: Deoxyribose = red Phosphate = blue A (Adenine) = green C (Cytosine) = yellow G (Guanine) = purple T (Thymine) = orange
Manipulate the nucleotide pieces until you find the best fit. Join the nucleotide molecules in your group together like a puzzle. Use tape to connect and reinforce the molecules. You now have a molecule of DNA.

The structure of DNA is actually in a DOUBLE HELIX arrangement.
DOUBLE HELIX means that the two long chains of nucleotides are arranged in a spiral like a twisted ladder.
Bring your molecule to the front of the room and join it to the molecules of the other groups. We now have one large DNA molecule.
