Which British scientist helped solve the structure of DNA by producing key X-ray diffraction images?

• A. Gregor Mendel
• B. Linus Pauling
• C. Rosalind Franklin
• D. James Watson

Answer: (C)

Verified step by step guidance

1. Understand that the question is about identifying the British scientist who contributed to solving the structure of DNA through X-ray diffraction images.
2. Recall that X-ray diffraction is a technique used to visualize the molecular structure of crystals, including biological molecules like DNA.
3. Recognize that Rosalind Franklin was the scientist who produced critical X-ray diffraction images of DNA, which provided key evidence for the double helix structure.
4. Note that Gregor Mendel is known for genetics principles but not for DNA structure, Linus Pauling proposed a different DNA model, and James Watson, along with Francis Crick, built the DNA model using Franklin's data.
5. Conclude that the correct answer is Rosalind Franklin, as her X-ray diffraction images were essential in solving the DNA structure.
