Austrian chemist Erwin Chargaff's research.
Erwin Chargaff arrived at his rule in the late 1940s after conducting research on the composition of DNA. His findings, known as Chargaff's rules, highlighted the complementary base pairing in DNA, such as the equal ratios of adenine to thymine and guanine to cytosine.
Erwin Chargaff discovered that the amount of adenine in DNA always equaled the amount of thymine. This observation is part of his rules, which state that in double-stranded DNA, the amount of guanine equals that of cytosine as well, highlighting the base pairing relationships crucial for the structure of DNA.
James Watson and Francis Crick are credited with the base pairing rules and DNA structure in general. Erwin Chargaff is credited with the rules of base pairs in that the number of pyrimidines is equal to the number of purines.
Erwin Chargaff is credited with discovering the nitrogenous bases of DNA and establishing the base pairing rules (Chargaff's rules) that helped lead to the discovery of the double-helix structure of DNA by Watson and Crick.
Base pairing proves Chargaff's rule, which states that in DNA, the amount of adenine equals the amount of thymine, and the amount of cytosine equals the amount of guanine.
Erwin Chargaff discovered the rule that the amount of adenine in DNA is always equal to the amount of thymine. This finding was a key breakthrough in understanding the base pairing rules in DNA.
Watson and Crick came up with the base-pairing rule for nucleic acids using Chargaff's rule that in DNA the percentages of adenine and thymine are equal, and the percentages of guanine and cytosine are equal. Refer to the related link below.

In 1950, Erwin Chargaff analysed the base composition of DNA composition in a number of organisms. He reported that DNA composition varies from one species to another so allowing for the ascertaining of differential.
Erwin Chargaff discovered that in DNA, the amount of cytosine is equal to the amount of guanine. This observation forms part of Chargaff's rules, which laid the foundation for understanding DNA base pairing.

Erwin Chargaff studied the base composition of DNA, noting that the amount of adenine equals the amount of thymine, and the amount of guanine equals the amount of cytosine. This led to the discovery of the complementary base pairing in DNA molecules.
