3. Correct: DNA is double-stranded; RNA is usually single-stranded.
- Explanation: DNA typically exists as a double helix of two complementary strands; RNA is usually single-stranded.
4. Correct: Dehydration synthesis.
- Explanation: Joining monomers into a polymer with release of a water molecule is dehydration (condensation) synthesis. Hydrolysis is the reverse (adds water to break bonds); hydrogenation is addition of hydrogen atoms.
