Answer:
In the table provided:
1. Chargaff (Figure 11-10):
Discovered that the amount of adenine (A) in DNA is equal to the amount of thymine (T), and the amount of guanine (G) is equal to the amount of cytosine (C). This discovery is known as Chargaff's rules.
2. Franklin (Figure 11-7):
Used X-ray diffraction to produce images of DNA, including the famous Photo 51. Franklin's work provided crucial evidence for understanding the double helix structure of DNA.
3. Watson and Crick (Figure 11-8):
Built a model of DNA that illustrated how the molecule could carry genetic information. This model was based on the X-ray diffraction images produced by Franklin and the base pairing rules discovered by Chargaff. Watson and Crick's model proposed the iconic double helix structure of DNA.
