Chargaff's analysis of the relative base composition of DNA was significant because he was able to show that
ArbitrLikvidat [17]

Answer:

C) The amount of A is always equivalent to T, and C to G

Explanation:

Chargaff's rule was given by the Austrian chemist, Erwin Chargaff in late 1940s. It explains the composition of the four bases i.e. Adenine(A),  Guanine(G), Thymine(T) and Cytosine(C) in a DNA molecule. According to it, purine and pyrimidine bases are always found in 1:1 ratio in a DNA molecule. A and G are purine and T and C are pyrimidine bases and a purine always forms a pair with pyrimidine base hence the amount of A will always be equal to T and amount of G will always be equal to C. This rule forms the basis for the Watson and Crick pairs in DNA double helix model.
