Final answer:
James Watson and Francis Crick are the two scientists credited with discovering the structure of DNA. They pieced together the structure based on X-ray diffraction data collected by Rosalind Franklin.
Step-by-step explanation:
James Watson and Francis Crick are the two scientists credited with discovering the structure of DNA.
They worked together at the University of Cambridge in the 1950s and were able to determine that DNA is made of two strands of nucleotides formed into a double helix. They pieced together the structure based on X-ray diffraction data collected by Rosalind Franklin, who discovered the X-ray diffraction pattern of DNA.
