I'm trying to draw a plasmid DNA with "sticky ends," which are just the zig-zaggy ends of an arc as seen below. http://www.di.uq.edu.au/sparq/images/proj4afig7.jpg I'm only trying to draw something similar to the image on the right, but with only one color on the arcs and no black outlines...

Many thanks. I haven't had a chance to try yet, but your detailed instructions make so much sense that I'm sure they'll work.

What's the easy way to create a 3D wireframe cylinder as seen below? The ExtrudeEffect extension looks promising, but I haven't had time to try it yet. Whether your solution is ExtrudeEffect or something else, I'd appreciate a brief but clear explantion of the steps involved. Many thanks. coumarin_r...
