1. Complete the following tasks using the DNA illustration.
- Color all of the phosphate groups pink.
- Color the deoxyribose sugar purple.
- Write a letter in each nucleotide to indicate which nitrogenous base it is (A, T, C, or G).
- Color each adenine green and label it with an A.
- Color each thymine orange and label it with a T.
- Color each cytosine blue and label it with a C.
- Color each guanine yellow and label it with a G.
2. Draw a line through the part below that is NOT one of the 3 parts of a nucleotide.
- Deoxyribonucleic acid
- Ribonucleic acid
- Nucleotide acid
3. Circle one word from each column below that best describes the shape of DNA.
- Shape: Double Helix
- Strands: Two
- Base: Nitrogenous
- Sugar: Deoxyribose
4. Circle the part(s) of the nucleotide that make up the sides of the DNA molecule.
- Phosphate group
- Sugar
- Nitrogen base
5. Circle the part(s) of the nucleotide that make up the center of the DNA molecule.
- Phosphate group
- Sugar
- Nitrogen base
6. Complete the base pairing rules.
- A pairs with T
- C pairs with G
