Who observed the constant ratios between Adenine and Thymine and Guanine and Cytosine in double stranded DNA?
James Watson
Francis Crick
Maurice Wilkins
Erwin Chargaff

The proposition of Double Helix model was also based on the observation of Erwin Chargaff that for a double stranded DNA, the ratios between Adenine and Thymine and Guanine and Cytosine are constant and equal one.
