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.
- Adenine binds with Thymine
- Cytosine binds with Guanine.
The base pairs present in the DNA makes its shape to be double helical.
