The DNA molecule is shaped like a twisted ladder. James watson and francis crick solved the structure of DNA. Other scientists like rosalind franklin and maurice wilkins can also contributed to this discovery.

In 1952, Rosalind Franklin produced an image of DNA that suggested it contained two strands twisted in a double helix with a phosphate backbone and bases inside.Franklin calculated the diameter of DNA, the distance between strands and bases, the angle of the helix, and the number of bases per coil.Watson and Crick used this information to build and accurate model of DNA.

When Franklin represented her X-ray data of DNA at Kings college, Watson was there but he didn’t pay attention to what Franklin was saying.
After that Watson and Crick were working on solving DNA structure at Cavendish Laboratory, where Wilkins showed the X-ray data to them that Franklin obtained.
So that is how they were able to confirm their 3-d structure of DNA.
