Final answer:
The correct order of contributions to the discovery of DNA is: DNA discovered, DNA studied with X-rays, human genetic code decoded, and 3D model of DNA developed.
Step-by-step explanation:
Correct Order of Contributions to the Discovery of DNA:
- DNA discovered
- DNA studied with X-rays
- Human genetic code decoded
- 3D model of DNA developed
DNA discovered represents the initial identification of DNA by Friedrich Miescher in 1869. Later, DNA studied with X-rays refers to Rosalind Franklin's work in the early 1950s, which provided crucial structural information. Subsequently, the human genetic code decoded entails the efforts of the Human Genome Project in the late 20th century, finally leading to the development of a 3D model of DNA.
