Answer 1

The correct answer is Watson and Crick

Key Points

The double helical model of the DNA molecule was proposed by James Watson and Francis Crick in 1953.
Their groundbreaking work was based on X-ray diffraction images taken by Rosalind Franklin and Maurice Wilkins.
The model explained how DNA replicates and how hereditary information is coded on it.
This discovery has had a profound impact on genetics and molecular biology.

Additional Information

James Watson and Francis Crick were awarded the Nobel Prize in Physiology or Medicine in 1962 along with Maurice Wilkins for their discoveries concerning the molecular structure of nucleic acids and its significance for information transfer in living material.
The double helix structure consists of two strands that wind around each other like a twisted ladder, with the bases adenine (A) pairing with thymine (T) and cytosine (C) pairing with guanine (G).
The discovery of the DNA double helix is considered one of the most important scientific discoveries of the 20th century.
Rosalind Franklin's critical contribution to the discovery was recognized posthumously as she passed away in 1958.
