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.
Chargaff's rules state that DNA from any cell of all organisms should have a 1:1 ratio (base Pair Rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine is equal to cytosine and the amount of adenine is equal to thymine. Discovered by Austrian chemist Erwin Chargaff.
Key conclusions from Erwin Chargaff's work are now known as Chargaff's rules. The first and best known achievement was to show that in natural DNA the number of guanine units equals the number of cytosine units and the number of adenine units equals the number of thymine units. In human DNA, for example, the four bases are present in these ...
Oct. 15—OHIO — As Ohioans head to the polls this election season, a topic of discussion is Issue 1, a proposed constitutional amendment to overhaul the state's redistricting process.
On March 24, 1997, the Supreme Court of Ohio ruled in a 4–3 decision that the state funding system "fails to provide for a thorough and efficient system of common schools," as required by the Ohio Constitution, and directed the state to find a remedy. [2]
