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. [1] A Bucovinian Jew who emigrated to the United States during the Nazi regime, he penned a well-reviewed [ 2 ] [ 3 ] autobiography, Heraclitean Fire: Sketches from a ...
Furthermore, Erwin Chargaff also printed a rather "unsympathetic review" of Watson's book in the 29 March 1968 issue of Science. In the book, Watson stated among other things that he and Crick had access to some of Franklin's data from a source that she was not aware of, and also that he had seen—without her permission—the B-DNA X-ray ...
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]
Here Comes Science is the fourth children's album and fourteenth studio album by American alternative rock band, They Might Be Giants, packaged as a CD/DVD set.The album is (as the title suggests) science-themed, and is the third in their line of educational albums, following 2005's Here Come the ABCs and 2008's Here Come the 123s.

Rollin Douglas Hotchkiss (September 8, 1911 – December 12, 2004) was an American biochemist who helped to establish the role of DNA as the genetic material and contributed to the isolation and purification of the first antibiotics.
