Question

Which is the best example of a scientific discovery resulting from new technology?
the discovery that elements can be grouped in a table on the basis of their properties
the discovery of atomic structure which led to the development of an electron microscope
the discovery of the structure of DNA, which occurred as the result of an X-ray image of a DNA molecule
the discovery that plant pigments can be separated and identified by using paper and a solvent

Answer 1

The discovery of the structure of DNA, which occurred as the result of an X‑ray image of a DNA molecule.

Reason: X‑ray crystallography (the new technology) produced Photo 51, which provided the critical data that made determining the double‑helix structure possible.
