RNA is primarily single-stranded, allowing it to fold back on itself and form complex secondary and tertiary structures. This is not possible with double-stranded DNA. The presence of uracil instead of thymine, the relative instability of RNA compared to DNA, and the substitution of deoxyribose in DNA with ribose in RNA are not directly responsible for RNA's ability to form complex shapes.
