<p>I didn't know where else to post this, sorry!</p>

<p>I have to make a 3D DNA model for my AP Bio Class: </p>

<p>It has to have all that stuff:</p>

<p>-Double Stranded
-Anti-Paralell
-All molecules (Deoxyribose, phophates, and all 4 bases)
-Double Bonds T-A
-Triple Bonds C-G
-10 bases per turn</p>

<p>And for extra credit:</p>

<p>-Show RNA that corresponds with 3'-5' strand
-RNA builds 5'-3' off DNA's 3'-5'
-Uracil in place of thymine
-Ribose must look different from deoxyribose</p>

<p>I can't use any kit to make it, it has to be all done my me. I have no idea what materials to use though. Appreciate if you could tell me what material to use for each part as well. Thanks</p>

<p>I'm glad I'm not in your class...
Styrofoam balls of various sizes + long toothpicks.</p>

<p>yeah, and maybe you could use different colored toothpicks for A,T,C,G, and U.</p>

<p>Wait I am pretty sure (iirc.. i may be wrong and this may be totally pointless) there are more H bonds between C and G than in A and T. If you have to show H bonds (you didn't say though) make sure you put that somewhere.</p>
