Answer: Chargaff's observation was an important clue to the A-T and G-C pairings that Watson and Crick eventually proposed. ... The structure of DNA suggested that the order of bases contains information. Because A is always paired with T and G with C, the order of bases on one strand determines the order on the other strand.
Explanation:
Chargaff’s data helped Watson and Crick determine the structure of DNA
through determining that it has a double helical structure.
Chargaff's rule states that a DNA consists of nitrogenous base pairs in which
the pairs have equal units and specific binding mate.
The base pairs present in the DNA makes its shape to be double helical.
