Step 1: Understanding the Concept:
The elucidation of the double helical structure of DNA is one of the most important scientific achievements of the 20th century.
Analyzing the historical context and the rules governing Nobel Prize nominations is essential to understand why key contributors were or were not recognized.
Step 2: Detailed Explanation:
Let us evaluate both statements individually:
- Statement (I) is correct: In 1962, James Watson, Francis Crick, and Maurice Wilkins were jointly awarded the Nobel Prize in Physiology or Medicine for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material.
- Statement (II) is incorrect: Rosalind Franklin made critical contributions to the discovery of the double helix through her high-resolution X-ray diffraction images of DNA (such as Photo 51).
However, she passed away from ovarian cancer in 1958 at the age of 37.
The primary reason she was not awarded the Nobel Prize in 1962 was because the statutes of the Nobel Foundation strictly prohibit the posthumous nomination or awarding of prizes (a rule established in 1974, but the committee had a long-standing policy of not awarding posthumous prizes unless the recipient died after the prize was announced).
While it is true that a single Nobel Prize cannot be shared by more than three individuals, the overriding factor preventing her nomination was her death in 1958, four years prior to the award.
Therefore, Statement (I) is correct but Statement (II) is incorrect.
Step 3: Final Answer:
The correct option is: Statement (I) is correct but Statement (II) is incorrect.
