My team actually has the opposite problem of you guys, maybe we can swap tips? For the reference sheet, I basically swiped most of the diagrams made available on "The Beery Twin's Story" webpage http://cbm.msoe.edu/scienceOlympiad/participant2.php and wrote paragraphs summarizing what it all meant. The provided research papers, while hard to read, are actually essential for the test. At the very least, I'd include the abstracts of the relevant research papers in the reference sheet. I wish that I included more of the papers' structure-description for the Regional exam, especially for the on-site model questions. I'd have over half of the reference sheet dedicated to information about this year's proteins and neurotransmitters, and the other half dedicated to general protein information, like the codon and amino acid tables mentioned above. Hope that's helpful!I've been having the same problem. We constantly see perfect scores on our models and then, like, 50% for our test. We're currently doing the same thing as you suggested. Make sure you have the obvious (a codon table, info about invitational, regional, state, and national proteins, amino acid table, structures of the neurotransmitters, etc.) if you don't already have it, because those can cost you a ton of points.This event forum is pretty inactive but going to ask anyway.
So our team at the past several competitions has been getting perfect or near perfect on both the prebuild and the onsite build. But the test portion of this event we consistently do sub-par on. Does anyone have any tips on doing better on the exam for this event? Right now our plan is to read a lot more research papers and add more information to our reference sheet. Any help is much appreciated as our teams is starting to feel a little stuck.
Also feel free to PM me if you want
Check the wiki for some info as well, if you haven't already.
Thank you for the help, that explains it perfectly and should help me on my next invitational (tomorrow, glad I checked ). That doesn't explain why the amino acid they had listed as an answer for our last invitational was 200 residues off, but what can you do...There is no problem with the kit. The scale is 2 cm per amino acid, which really means that there are 2 cm between each amino acid. If you go on Jmol and color one amino acid you will see that the color covers one bend and halfway to the bend on either side. So each amino acid is represented by the turn - not the connection. The backbone structure connects amino acids linearly, rather than creating smooth turns like in the cartoon visualization. So, getting back to the kit, you need 2 cm between each amino acid. Say the protein was from amino acids 5 to 9 (hypothetically), that would mean your structure would be as follows with the dashes representing the 2 cm of tuber you need.A team from our state noticed the same issue. You can glue on your red and blue caps so they are only attached to 1 cm of the toober. Assuming that the caps are 2 cm each this will add 2 cm total to your protein.We have purchased the 3 D molecular design’s 2015-2016 Science Olympiad Protein Modeling Event Kit (pre- build Kit). The site says it is for 168 amino acids but this year’s protein needs 169 and we found the mini-toobers are short by 2 centimeters. Has anyone else ordered the kit and had the same problem? If so, how did you add the two centimeters?
5 - 6 - 7 - 8 - 9
That's four dashes, 4 * 2 = 8 cm of tuber. More simply, (9-5) * 2 = 8. In the case of this years protein, we have to build amino acids 93 - 261. So, (261- 93) * 2 = (168) * 2 = 336 cm of tuber, which is what the kit provides.
I know it's confusing because there are 169 amino acids but you have to understand that the first and last amino acids are at the ends of the tuber. And when you restrict the amino acids visualized in Jmol, the program will eliminate one cm of backbone connecting to amino acid 92 and one cm of backbone connecting to amino acid 264, which is why the kit provides 2 cm less tuber than you might expect.
Usually it's split into two parts: Protein general multiple choice and protein specific frq. Protein general is usually basic protein structure (where's the side chains in an a-helix?), amino acids (which amino acid might do x), or protein folding (what do chaperonins do?). Protein specific will be over sepiapterin reductase, the Beery Twins, and the competition specific protein (invitational, regional, state, or national level, depending on which one you're going to). The questions will be something like: What does this specific amino acid do in the reaction? How does inhibition work in the protein? How does this inhibitor differ from the other? etc. Make sure to read the entire paper, because some answers might be obscure.What sort of questions are they going to ask us about for the written test? I couldn't find any practice tests relevant to this year's protein
