WebIn molecular biology and genetics, GC-content (or guanine-cytosine content) is the percentage of nitrogenous bases in a DNA or RNA molecule that are either guanine (G) … Chargaff's rules state that in the DNA of any species and any organism, the amount of guanine should be equal to the amount of cytosine and the amount of adenine should be equal to the amount of thymine. Further a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C) should exist. This pattern is found in both strands of the DNA. They were discovered by Austrian-born chemist Erwin Chargaff, in the late 1940s. WebIt has been found experimentally 3,4 that the ratio of the amounts of adenine to thymine, and the ratio of guanine to cytosine, are always very close to unity for deoxyribose nucleic acid.

WebIn the remaining 30% half will be Cytosine (15%) and remaining half will be Guanine(15%). The amount of Adenine is equal to thymine as Adenine always forms bond with Thymine. So if there are 10 Adenines there will be 10 Thymines. In the same way number of Guanine will be equal to number of Cytosine. Adenine-35%. Thymine-35% Guanine-15% … WebThis is the basis for Chargaff’s rule; because of their complementarity, there is as much adenine as thymine in a DNA molecule and as much guanine as cytosine. Adenine and thymine are connected by two hydrogen bonds, and cytosine and guanine are connected by three hydrogen bonds.
