Help in modeling beads on a string DNA structure from a single nucleosome

I am trying to model the beads on a string DNA organization and I modeled one nucleosome successfully and I trying to duplicate it to make it like beads on string. I have been trying for days but with not luck. I tried duplicating it, applied array modifier and created a particles system but none of this worked.

Here is an image of the nucleosome I made with simple shaders to differentiate between the different histones.

I am applying a curve modifier to the DNA to bend it around the histones and make it look organic.

Any help?

The nucleosome I modeled

and here is an image of the model I want to make.

every blue octamer is a nucleosome just like the one I made

how can I duplicate my nucleosome into this structure?

there is a DNA string in the wiki for array
did you check it out ?

looks like the new page does not have it !

https://docs.blender.org/manual/en/latest/modeling/modifiers/generate/array.html

lost the old page with DNA example

may be some one has another link for it or a sample file

happy bl

here is a video tut on how to make it

hope it helps

this is a great video in regard to DNA but it doesn’t mention the proteins (in this case the 4 colored meshes) or how to handle them :3

is there any sort of symmetry for this model ?

it could help find a faster way to do it !

have not done the DNA model in a long time and I cannot find it !

happy bl

no there’s any symmetrical regions in this model.

do you have a biological background or used to make biological models and animations?

sorry not in BIO at all !

but I 'v seen a few threads on Bio
I can find other threads for BIO
may be one can have some tips or other links

but using curves should work for the DNA part
and for the blue parts you could use Verts duplicate with a simple mesh
but this has to be done manually.

No guarantees here because I don’t have your .blend file but couldn’t you add an additional string of vertices and use a Hair Particle System to spawn the proteins?
