Directions:

The 2020-21 Pre-Build Model should represent amino acids 31 - 145 of chain A of the cytidine deaminase protein based on the PDB file 5keg.pdb. This section will require a toober that is 228cm long at the scale of 1 amino acid = 2cm.

NOTE: This is a different structure/sequence than originally stated in the
Science Olympiad rules. The correct structure/sequence is amino acids 31-145 of chain A of 5keg.pdb

The pre-build model is worth 40% of a team's final score for the event. The pre-build model will be created using a purchased "pre-build" Mini-Toober kit from www.3dmoleculardesigns.com, or with found materials of the participant's choosing such as KwikTwist tie-down ropes. The same pre-build model will be used at each level of the competition (invitational, regional and state) and participants will take their pre-build model home after each event.
