Study Notes
DNA and RNA Structure
- The nitrogenous base that forms a glycosidic bond with the 1' carbon of deoxyribose is a nucleobase (adenine, guanine, cytosine, or thymine).
RNA Composition
- Uracil is the nitrogenous base present in RNA but not in DNA.
Phosphodiester Bond
- A phosphodiester bond forms between the phosphate group and the 3' and 5' hydroxyl groups of the deoxyribose sugar.
Common Components
- The components common to both DNA and RNA nucleotides are a nitrogenous base, a five-carbon sugar (deoxyribose in DNA and ribose in RNA), and a phosphate group.
Nucleotide Sequence
- The linear sequence of nucleotides forms a polynucleotide chain or a single-stranded DNA or RNA molecule.
