What are the main differences between RNA and DNA? Select all that apply.
RNA does not contain thymine. Instead, it has a nitrogenous base called uracil.
RNA contains the 5-carbon sugar ribose instead of deoxyribose.
RNA contains weak hydrogen bonds between its phosphate groups and 5-carbon sugars.
DNA is usually double-stranded, while RNA is usually single-stranded.

Correct choices: 1, 2, and 4.
- RNA uses uracil (U) instead of thymine (T).
- RNA has the sugar ribose; DNA has deoxyribose (lacks one oxygen).
- DNA is typically double‑stranded (double helix); RNA is usually single‑stranded (though it can form internal base‑paired structures).
Statement 3 is false: the sugar–phosphate backbone is held together by covalent phosphodiester bonds, not hydrogen bonds; hydrogen bonds occur between complementary bases.
