DNA Model

Building a Model of Deoxyribonucleic Acid

Please note: If the class is getting short on time, this project may be sacraficed so we can focus on the California Standards.

The building of a model is a great way to help a student see and understand something that is too small for them to see and touch. DNA is extremely small for us to see, and even when we do, it is still difficult for students to get a clear picture or understand how it works. Models, such as the ones we will make, will assist us in seeing the order that exists in life.
The models of DNA can be built out of any materials that the student desires! I have even had some students turn in edible DNA strands while others were amde out of nuts and bolts! Ther is no limit as to what materials may be utilized.

Here are the requiremnts for the models.
1. Must include Hydrogen bonds, Phosphates, and Sugar bonds.
2. Each Base must match up with the appropriate opposite.
3. There must be a legend or key naming each part of the model.
4. The model must be able to hang from a hook, or be free standing.
5. The model must be interesting to look at.

(Please note that Thymine (T) is replaced as Uridine (U). In your models, use these same orders, but put a T where the U is located.)

Example: Valine - GUU, you would have Valine - GTT

Grading

In order to receive an '5'
Model will be accurately done.
Bases will be in corrct order of Amino Acids (these are called CODONS).
There will be no less than 15 links in the chain.
The model and key will easily identify the parts of DNA.
The student will have put forth great effort.

The model will do a complete 360 degree rotation.

In order to receive a '4'
Model will be accurately done.
There will be no less than 15 links in the chain.
The model and key will easily identify the parts of DNA.
The student will have put forth good effort.

In order to receive a '3'
Model will be accurately done.
There will be no less than 10 links in the chain.
The model and key will easily identify the parts of DNA.
The student will have put forth the effort to complete the assignment.
The project meets the requirements for a '5' but is late.

In order to receive a '2'
The model was completed with few errors.
The key and model can be understood.
There are nine or less links in the chain.
The student put forth little effort.
The project meets the requirements for a '4' but is late.

In order to not receive a passing grade:
The student puts forth minimal effort.
