DNA Model Project
Biology 1-2
Due:
Worth 100 Points
During the course of this week you have been give n information on how DNA molecules code
for specific amino acids and proteins. During this project you will use this information to create
a specific DNA molecule that codes for three amino acids. For this assignment you will work in
groups of three students. Groups will not be assigned so choose your partners wisely. Remember
LATE WORK ON PROJECTS IS NOT ACCEPTED!!
Requirements: Model must
 Be in 3-D
 Be in the form of a double helix
 Show correct base pairing
 Contain a sugar-phosphate backbone
 Represent all four nucleotides by a different color or shape.
 Have a key indicating which nucleotide is which
 Code for a start codon, three amino acids, and a stop codon.
o This means that your model must be at least 15 base pairs long!!
 Must be created during class time.
This assignment will be done during class time. The following is a timeline of events for the
next week and a half:
Friday 1/8/10 – Following quiz assign responsibilities and materials to group members.
Plan for work the following week.
Monday 1/11/10 through Thursday 1/14/10 – The entire class period will be given for
DNA construction.
**NOT HAVING MATERIALS READY FOR THESE DAYS WILL RESULT
IN AN INDIVIDUAL BOOK WORK ASSIGNMENT. (At no point should a
group tell me “We’re working on it at home.”)
Friday 1/15/10 - DNA models are due and presented to the class. Late work will not be
accepted. Not having a project will result in a zero!!
