| Which ratio is constant for DNA? |
A + U / G + C A + C / U + G
A + T / G + C
A + G / T + C
|
| A + G / T + C |
| The molar concentration of purine bases A and G is equal to the molar concentration of pyrimidine bases T and C because one of each type makes up a base pair. Because of base pairing rules, A = T and G = C. The specific A – T and G – C content varies from species to species. But in any one species the ratio is constant. |
