The average energy of each hydrogen bond...

The average energy of each hydrogen bond in A-T pair is x kcal `mol^(-1)` and that in G-C pair is y kcal `mol^(-1)`. Assuming that no other interaction exists between the nucleotides, the approximate energy required in kcal `mol^(-1)` to split the following double stranded DNA into two single strands is

[each dashed line may represent more than one hydrogen bond between the base pairs ]

A

10x+9y

B

5x+3y

C
