WebSep 15, 2024 · 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 strand length. Table of Contents show What is Chargaff’s rule Short answer? 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.
