15 lut 2021 · DNA Model – Cut and Paste Nucleotides. This digital modeling activity allows students to build a DNA model by dragging the individual parts into a completed diagram. Structures, such as deoxyribose, phosphate, and the nitrogen bases are shown.
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).
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. 3) Using the small symbols (squares, circles and stars) on the structures as
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.
Students construct a paper model of DNA by cutting nucleotides from a pattern, coloring and then taping to a sheet. Worksheet includes questions on DNA structure.
Worksheets are provided to support them to evaluate how well the model represents the structure of DNA. Easy to download and print PDF resource. For more AQA Inheritance, Variation and Evolution resources click here.
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.
