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 extra credit
towards your semester grade. Your model needs to be able to hang from the ceiling and may
not include any food that will spoil. The more professional and attractive/sturdy your project,
the more points you may earn. The maximum extra credit you may receive is 50 points. Because
this is EXTRA credit, you may not earn any points if your project is poorly constructed or
thrown together, you must put in the extra effort to gain credit!
The following is a rubric for grading (pass in with project)
