If you get stuck on anything in C4D let me know. At this point I can call myself knowledgeable in that app and everything I don't sculpt is made in C4D. The UV Mapping is garbage btw. I would do it in Roadkill or ZBrush. Otherwise you will have to path select the seams and front project with possible pinning to prevent overlapping. A decent free beginners resource for C4D is "greyscalegorilla." They have basic videos on quite a few things. Not professional but you get what you don't pay for...

As for the DNA I made one a while back. I made the two splines and reversed one. Then I ran an index through Xpresso and point constrained splines to match the vertex numbering of the spiral splines with user data stating the start position and to move down in the hierarchy.
