The correct statement with regard to the secondary structure of DNA/RNA is:

Solution & Explanation

Related Formula
DNA: Double helix (Bases: A, G, C, T), RNA: Single stranded (Bases: A, G, C, U)
Core Logic

DNA secondary structure consists of a double-stranded helix holding thymine (T) along with adenine, guanine, and cytosine. RNA is typically single-stranded containing uracil.

Step 1: Conclusion

Statement (3) is correct.

Pattern Recognition

DNA = Double stranded + Thymine; RNA = Single stranded + Uracil.
