Answer 1

Correct answer: "DNA is a double-stranded molecule, while RNA is a single-stranded molecule; DNA contains the sugar deoxyribose, and RNA contains ribose."

Brief explanation: DNA is a double‑helix with deoxyribose and uses thymine; RNA is usually single‑stranded with ribose and uses uracil. DNA primarily stores genetic information; RNA (mRNA, tRNA, rRNA) functions in gene expression and protein synthesis.
