Which scientists created the 3D structure of DNA:
A
Watson and crick
B
hershey and chase
C
griffith and chargaff
D
pauling and franklin
Explanation: 

Detailed explanation-1: -The discovery of the double helix structure of DNA is most often attributed to James Watson and Francis Crick. Using Chargaff’s rules and the works of English scientists Rosaline Franklin and Maurice Wilkins, they built a 3D model of the double-helical structure of DNA.

Detailed explanation-2: -They used X-ray crystallography to identify that DNA is made up of two strands wrapped around each other to produce a double-helical structure. Along with X-ray crystallography, they also made use of Chargoff principles.
