Final answer:
Francis Crick and James Watson acquired Rosalind Franklin's unpublished data on the structure of DNA.
Step-by-step explanation:
Francis Crick and James Watson acquired Rosalind Franklin's unpublished data on the structure of DNA.
Franklin was using X-ray diffraction methods to understand the structure of DNA, and Watson and Crick were able to piece together the puzzle of the DNA molecule based on her data.
However, it is worth noting that Franklin did not willingly share her data with Watson and Crick; they obtained it without her knowledge or permission.
