- A \(1.2\)
- B \(3,2\)
- C \(3,1\)
- D \(2,1\)
Answer & Solution
Correct Answer
(B) \(3,2\)
Step-by-step Solution
Detailed explanation
The only possible pairing in DNA are between \(\mathrm{G}\) (guanine) and \(\mathrm{C}\) (cytosine) through three \(\mathrm{H}\)-bonds i.e., \((\mathrm{C} \equiv \mathrm{G})\) and between A (adenine) and \(\mathrm{T}\) (thymine) through two \(\mathrm{H}\)-bonds (i.e.,…
