In geometry a double helix (plural helices) typically consists of two congruent helices with the same axis, differing by a translation along the axis, which may or may not be half-way.

Can someone please describe what a double helix looks like? I think it looks like fusilli pasta. Is this correct? I'm having a lot of trouble understanding what DNA looks like.
Please help, thank you.
I am visually impaired by the way.
