WebSep 15, 2024 · What is Chargaff’s rule and why is it important? September 15, 2024 by Alexander Johnson. The Chargaff’s rule states that the number of purines and pyrimidines in the DNA exist in the ratio 1:1. It provides the basis of base pairing. With the help of this rule, one can determine the presence of a base in the DNA and also determine the ... Webaccording to chargaff's rule of base pairing which of the following is true about DNA? A=T and C=G the bonds that hold the two strands of DNA together come from WebChargaff's rules for distribution of nitrogenous bases-%A approximately equals the %T and the %G approximately equals the %C in both species - If Chargaff's equivalence rule is valid, then hypothetically we could extrapolate this to the combined genomes of all species on Earth (as if there were one huge Earth genome). In other words, the total ... dentist for wheelchair bound
