Final answer:

The original published articles describing the structure of DNA were authored by James Watson and Francis Crick, who developed the double helix model presented in April 1953 in Nature. Rosalind Franklin's X-ray diffraction images and Chargaff's rules greatly influenced their work.

Step-by-step explanation:

The original published articles describing the structure of DNA were authored by James Watson and Francis Crick. In the 1950s, Watson and Crick worked together at the University of Cambridge, England, to determine the DNA structure. They utilized vital information from other researchers, including the X-ray diffraction images from Rosalind Franklin's work and Chargaff's rules, to develop their revolutionary double helix model.

In 1962, the Nobel Prize in Physiology or Medicine was awarded to James Watson, Francis Crick, and Maurice Wilkins. Rosalind Franklin had also made significant contributions to understanding the DNA structure, but she had passed away by the time the Nobel Prize was awarded, and as Nobel Prizes were not awarded posthumously at that time, she did not receive recognition.

Watson and Crick's groundbreaking article titled "Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid" was published in the journal Nature in April 1953, where they presented their model of the DNA double helix.
