Identify the two scientists who first obtained an X-Ray pattern of the DNA molecule.

The two scientists who first obtained an X-ray pattern of the DNA molecule are Rosalind Franklin and Maurice Wilkins. Their work in the early 1950s played a crucial role in the discovery of the DNA structure.

Rosalind Franklin conducted X-ray diffraction experiments that produced images showing the helical structure of DNA. One of her most famous images, known as Photo 51, provided critical insight into the dimensions and shape of the DNA molecule. Maurice Wilkins worked alongside Franklin and also contributed to the understanding of DNA's structure through his own research and X-ray diffraction studies.

Ultimately, their findings laid the groundwork for James Watson and Francis Crick to propose the double helix model of DNA in 1953, but it was Franklin and Wilkins' earlier X-ray work that helped illuminate the molecular structure of DNA.
