DNA & RNA 3D Model

Objective: Build scientifically accurate models of DNA and RNA molecules. Use your book, notes, and any other resources as background information. This will count as a 100 point project/major grade.

The following is a rubric for grading (pass in with project)

DNA Portion:

1. Project is scientifically accurate based on key and overall structure:

a. The correct bases are connected: _____/6

b. Phosphates and sugars are alternating correctly: _____/6

c. Everything is attached where it is supposed to be: _____/6

d. Model is 3 dimensional: _____/6

e. Model is in the form of a double helix (physically twisted): _____/6

2. Model contains at least 8 base pairs: _____/8

3. Deoxyribose sugars and phosphate groups are represented with different colors and/or

structures: _____ /6

4. All 4 nitrogen bases are represented by different colors and/or structures: _____ /6

5. Hydrogen bonds are represented clearly: _____ /6

RNA Portion:

6. Project is scientifically accurate based on key and overall structure:

a. 3 dimensional: _____/6

b. Phosphates and sugars are alternating correctly: _____/6

c. Correct bases shown: _____/6

d. Everything is attached where it is supposed to be: _____/6

e. Corresponds to one half of your DNA model: _____/8

7. A CLEAR key is provided for all components (neat and easy to follow): _____ /12

Total Points earned = ____/100
