Study Notes
RNA Structure
- RNA is a single-stranded molecule composed of ribonucleotides
- Ribonucleotides in RNA contain ribose (pentose sugar), one of four nitrogenous bases (A, U, G, C), and a phosphate group
- Ribonucleotides are linked by phosphodiester bonds
DNA vs RNA
- DNA is typically double-stranded, while RNA is typically single stranded
- RNA can fold upon itself due to complementary base pairing within the molecule
- These folds create a three-dimensional structure
