Chargaff To determine whether DNA is responsible for differences between species Used paper chromatography to isolate DNA, and then analyzed the nucleotides via spectrophotometry Ratios of A:T and G:C in DNA are always both 1:1 Different species have different ratios of A and T to G and C (1 gen 1944 anni – 1 gen 1952 anni)
