|
|
the shape of a double helix
|
|
|
a protein molecule
|

|
the genetic material
|
|
|
a short molecule

Explanation:
Detailed explanation-1: -In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they called a “double helix, ” in the journal Nature. For this breakthrough discovery, Watson, Crick, and their colleague Maurice Wilkins won a Nobel Prize in Physiology, or Medicine, in 1962.
Detailed explanation-2: -Taken in 1952, this image is the first X-ray picture of DNA, which led to the discovery of its molecular structure by Watson and Crick. Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule.
