Model Diagram

This lab will be done outside of class.

In teams of no more then three build a model of a DNA molecule using materials of your choice (purchased kits prohibited). Your model must be as follows:

• The model must be free-standing.
• The model must show the twisted double helix shape
• Size no larger then 30 cm wide and deep by 60 cm tall
• The sugar and phosphate molecules must alternate along the two strands.
• The 4 nitrogen bases must be joined accurately.
• Draw a diagram of your model and label all parts.
• Include model, drawing and rubric to be turned in.

Honors Biology: In addition to the model above

• show phosphodiester bonds
• show hydrogen bonds
• indicate the 5' to 3'  & 3' to 5' directions
• use this (right side) sequence of nitrogen bases to construct your model
