Question

what is the connection of william bragg to the eventual solving of the dna mystery?

1. he is the scientist who got credit for the work because his lab was used by watson and crick for research.
2. he authorized additional work on the topic and pushed watson and crick to continue pursuing an answer.
3. his contact with other scientists allowed information to be shared that was then used by watson and crick.
4. his work served as the basis of what became the final model and what watson and crick used as their inspiration.

Explanation:

To determine the correct answer, we analyze each option:

• Option 1: William Bragg's lab wasn't the one used by Watson and Crick for DNA research in the way described, so this is incorrect.
• Option 2: There's no indication Bragg authorized work or pushed Watson and Crick in this manner, so this is wrong.
• Option 3: Bragg's contact with scientists isn't the main connection to solving the DNA mystery.
• Option 4: William Bragg's work in X - ray crystallography (which was foundational for understanding molecular structures) served as a basis and inspiration for Watson and Crick's final DNA model. This aligns with the historical context of DNA structure discovery, where X - ray crystallography data (including work related to Bragg's contributions to the field) was crucial.

Answer:

1. His work served as the basis of what became the final model and what Watson and Crick used as their inspiration.
