A) The ratio of purines to pyrimidines is roughly equal in all tested organisms.
B) The ratio of A to T is roughly equal in all tested organisms.
C) The ratio of A + T and G + C is roughly equal in all tested organisms.
D) Both [a] and [b]
Correct Answer: D
Solution :
[d] Chargaff found that the relative ratios of purine to pyrimidines were equal. Adenine and guanine are purines and cytosine and thymine are pyrimidines; therefore, ratios of adenine and thymine should be equal. Chargaff also found that there is no conserved ratio between specific pairs (\[e.g.,A+TandG+c\]).You need to login to perform this action.
