Naily [24]

Answer: The correct answer is A) A+C=G+T

According to Watson and Crick base pairing-

In a double stranded DNA molecule, Adenine pairs with Thymine and Guanine pairs with Cytosine. This means that number of Adenine in one strand is equal to the number of thymine in the complementary DNA strand. Similarly, the number of Cytosine in one strand is equal to the number of Guanine in the complementary strand.

Thus, the total number of Adenine and Cytosine in one strand becomes equal to the total number of Guanine and Thymine in the complementary strand.

This can be mathematically written as- A+C = G+T

Thus, option A) is the right answer.
