If the ratio of (A+G/T+C) in one strand of DNA is 0.70, what is the same ratio in complimentary strand?

Answer 1

In a complimentary strand, A is changed to T, T is changed to A, G is changed to C, and C is changed to G.

For the given ratio:

(A+G)/(T+C)

the complimentary strand have the inverse ratio of:

(T+C)/(A+G)

We know that the first ratio is equivalent to 0.7, which can be written as 7/10. To get the ratio of the complimentary strand, we take the inverse of this, which gives us 10/7, which can be simplified to 1.43
