Apologies in advance for a simple question from a new user.
I’m a scientist that does work on nucleosome fibers. I would like to create a blender model of a nucleosome fiber to which I will eventually add bones so I can easily manipulate and animate. It is basically long tube wrapped around a fat cylinder. The model will use a cylindrical tube for the DNA and a fat cylinder for the protein core. I’ve tried a couple of simple steps (using twist on a circle, etc), but I’ve had little luck. The details of the model (translating 1 blender unit=1 nm) are that the protein cylinder (the easy part) will be 10x6 in size and the DNA tube (minor radius of 1) should wrap around the cylinder 1.65 times.
I’m sure I can do it all by hand with extrusions, but I’d like to be a bit more precise and add some constraints to the DNA as it exits the nucleosome (should not bend in an arc of a radius of 8 units or less).
I’ve included a picture of the fiber in the post (as a new user I can’t post a link), but if you look on wikipedia for nucleosome, you can grab a high resolution picture.
Thanks for any help! I’m loving this program so far.
