Final answer:

Chargaff's team utilized base composition analysis to compare nitrogenous base amounts in DNA samples by determining the relative concentrations of A, T, C, and G based on Chargaff's rules.


Explanation:

Chargaff's team used a technique called base composition analysis to compare the relative amounts of nitrogenous bases in DNA samples. This involved determining the concentrations of the A, T, C, and G bases by hydrolyzing DNA from various species into individual pyrimidines and purines. Based on Chargaff's rules, if a DNA sample has 22% thymine, then adenine would also be 22%. Since A equals T and G equals C, cytosine and guanine would also be 28% each to maintain the balance.
