Molecular structure of RNA (video) | Khan Academy
DNA and RNA have different sugar backbones: deoxyribose for DNA and ribose for RNA. Notably, RNA has uracil instead of thymine as a nitrogenous base.
Nucleic acids (article) | Khan Academy
DNA and RNA also have different structures; DNA's phosphate-sugar backbone contains deoxyribose, while RNA's contains ribose. While DNA is double-stranded and has the nitrogenous bases adenine, …
