KEY CONCEPTS. DNA is a polymer of nucleotide monomers, each consisting of a phosphate, a deoxyribose sugar, and one of four nitrogenous bases: adenine (A), thymine (T), guanine (G), or cytosine (C). The nucleotides of DNA are arranged into a double helix based on the rules of base complementarity.
ACTIVITY –MAKING A MODEL OF DNA. 1) Colour the individual structures as follows: Adenine (A) = red Thymine (T) = green Guanine (G) = blue Cytosine (C) = yellow Phosphate (P) = brown Deoxyribose (D) = purple 2) Cut out each structure.
Karen Mayes. DNA Paper Model Activity . Level: Grade 6-8. Students will be able to: Identify the component molecules of DNA. Construct a model of the DNA double-helix. Identify which bases are found in pairs in the DNA double-helix. Predict the appearance of a complimentary strand of DNA when given half of a double-helix molecule.
Modeling the Structure of DNA student handout. INTRODUCTION. In this activity, you will build your own model to understand how DNA works. DNA is a simple molecule made up of four types of chemical building blocks called nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G).
Construct the right side of your DNA molecule by putting together in sequence a cytosine, thymine, guanine and adenine nucleotide. Complete the left side of the DNA ladder by adding complementary nucleotides or nucleotides that fit. Your finished model should resemble a ladder.
Build a Paper Model of DNA. Fill in the names of the bases on the model shown to the right, or use the detailed model that shows all the atoms in each nucleotide (back side of paper). Cut out the model. Fold all long creases first.
DNA Model. ESTIMATED LENGTH: 85-115 MIN* . In this small group activity, MIDDLE SCHOOL students will make an edible model of a DNA double helix. ugar-phosphate backbone. As students put together their DNA model, they will learn about the base pairing rules and how DNA encodes each organism.
