Which of the following is not consistent with the base pairings in a double stranded DNA molecule?
1. The number of C equals the number of G
2. The number of A equals the number of T
3. The amount of purine is equal to the amount of pyrimidines
4. The ratio of (G+C) to (A+T) is same for each species
The amount of A + G will be equal to T + C in a double stranded DNA molecule.
