Vedclass · Answer

(C) According to Chargaff's rules for double-stranded $DNA$,the amount of adenine $(A)$ equals the amount of thymine $(T)$,and the amount of guanine $(G)$ equals the amount of cytosine $(C)$.Therefore,$(A + G) = (T + C)$ and $(A + C) = (T + G)$.Consequently,the ratios $(A + G) / (C + T) = 1$ and $(A + C) / (T + G) = 1$ are constant for all species.However,the ratio $(G + C) / (A + T)$ varies significantly between different species,as it depends on the specific base composition of the organism's genome.

Which of the following ratios is generally not constant for all given species?
