Understand that the question is about the historical discovery of the DNA double-helix structure, which is a fundamental concept in genetics.
Recall that the double-helix model of DNA was proposed in 1953, marking a major milestone in molecular biology.
Identify the key scientists involved in this discovery: James Watson and Francis Crick are most famously credited with establishing the double-helix model.
Note that while other scientists like Rosalind Franklin contributed critical X-ray diffraction data, the formal model is attributed to Watson and Crick.
Therefore, the correct answer is James Watson and Francis Crick, as they published the double-helix structure of DNA in 1953.
