Why are you doing this, Cornell?

Quite frankly, I think why you're doing this is so we can get an independent sense of how to handle situations that are just tossed at us. Also, you're trying to give us new things to try, and new ideas about what we may want to do. And maybe you think we'll do better with a push like this.

I've decided to make a DNA chain, type B.
Every model type essentially shows the different structure and materials of the chain in question, the CPK showing the atomic structure, Ball and stick molecular, the contact surface model shows the outside of the protein, the biological unit to display the life form.

The colors in the CPK and ball and stick model represent the atoms Oxygen, Hydrogen, and Carbon.

The Protein will have a chain of nucleic acids in the description if it is biological.

A Capsid is the shell of protein that protects the nucleic acids.

Ambient Occlusion shows how detailed and textured proteins and molecules are, in a realistic manner.

PDB Info-
Molecule Name: DNA
PDB ID Number: 1BNA
Authors:
Drew, H.R.,  Wing, R.M.,  Takano, T.,  Broka, C.,  Tanaka, S.,  Itakura, K.,  Dickerson, R.E.
Type: dna
Number of Chains: 12
What: It is a chain of nucleic acids which instruct proteins to carry out specific tasks in cells.
Where/what is the significance?: It is almost the literal blueprint to life, found in the nucleic material of all cells. 
Structure: It's structure makes it very easy to intertwine together and pack together to hold more information.
Diseases: When this protein is flawed, it gives instructions for cells to replicate with no control. This eventually becomes cancer, which can be fatal. If the structure of this molecule is flawed, then cancer is more likely to occur.
