Question

You have performed an analysis to determine the proportions of each of the four nucleotide bases in the DNA of several tissue samples from various species. The results appear in the following table. % adenine (A) % guanine (G) % thymine (T) % cytosine (C) Human 31 20 30 19 Chicken 28 21 29 22 Yeast 32 18 33 17 E. coli 26 25 24 25 Which conclusions can you draw from this data? The proportion of pyrimidines is roughly equal to the proportion of purines. The proportion of A is roughly equal to the proportion of T. The proportion of G is roughly equal to the proportion of C. The proportion of A–T base pairs is roughly equal to the proportion of G–C base pairs.
