Question

In 1953, Watson and Crick discovered the structure of DNA by examining data from many different experiments. How did using Chargaff’s data help Watson and Crick determine the structure of DNA ?

Answer 1

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:

Answer 2

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.
