The following table is a representative sample of Erwin Chargaff's 1952 data, listing the base composition of DNA from various organisms and support both of Chargaff's rules. [14] An organism such as φX174 with significant variation from A/T and G/C equal to one, is indicative of single stranded DNA.
Erwin Chargaff's work in 1950 demonstrated that, in DNA, the bases guanine and cytosine were found in equal abundance, and the bases adenine and thymine were found in equal abundance. However, there was no equality between the amount of one pair versus the other. [3] Chargaff's finding is referred to as Chargaff's rule or parity rule 2. [3]
Erwin Chargaff (11 August 1905 – 20 June 2002) was an Austro-Hungarian-born American biochemist, writer, and professor of biochemistry at Columbia University medical school.

Brainchild is an educational series targeted toward a young audience that conducts various scientific experiments. Experiment topics include dreams, emotions, superheroes, motivation, the deep sea and gravity. [1] [4]
Later, Erwin Chargaff(1950) discovered that the makeup of DNA differs from one species to another. These experiments helped pave the way for the discovery of the structure of DNA. In 1953, with the help of Maurice Wilkins and Rosalind Franklin's X-ray crystallography, James Watson and Francis Crick proposed DNA is structured as a double helix. [1]
