What is the size difference between sugars and phosphates in DNA (double helix)?

Question

I'm working on a project for DNA, and I need to build a model of a double helix. On my assignment sheet it says "Sugars and Phospates correctly and consistently sized relative to eachother"

Answer 1

The sugars and phosphates in the backbone of DNA are the same. All of the sugars are the same size, and the phosphate bonds are the same size.
