Answer:
In 1952 Rosalind Franklin provided a DNA illustration indicating that there were two strands in a double helix twisted with a backbone of the phosphate and bases within. There was an mistake. This was used by Watson and Crick to develop a precise DNA model.
Explanation:
Answer:
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.
