Question

photo 51 is a picture of the structure of dna that was used to create a model of dna. who created the photo?
james watson and francis crick
erwin chargaff
rosalind franklin
friedrich miescher

Explanation:

To determine who created Photo 51 (the X - ray diffraction image of DNA's structure), we analyze each option:

• James Watson and Francis Crick are known for developing the DNA double - helix model, not for taking Photo 51.
• Erwin Chargaff is associated with Chargaff's rules about DNA base pairing, not with creating Photo 51.
• Rosalind Franklin, through her X - ray crystallography work, produced Photo 51, which was crucial for understanding DNA's structure.
• Friedrich Miescher is credited with discovering nucleic acids, not with creating Photo 51.

Answer:

C. Rosalind Franklin
