  • Nucleoside

    A molecule formed by attaching a nitrogenous base to a sugar via a glycosidic bond, lacking any phosphate group.
  • Nucleotide

    A compound consisting of a nucleoside linked to a phosphate group at the 5' carbon of the sugar.
  • Nitrogenous Base

    A ring structure, either purine or pyrimidine, that pairs with a sugar to form nucleosides.
  • Pyrimidine

    A single-ring nitrogenous base category, including cytosine, uracil, and thymine, with nucleosides ending in 'idine'.
  • Purine

    A double-ring nitrogenous base category, including adenine and guanine, with nucleosides ending in 'osine'.
  • Ribose

    A five-carbon sugar present in RNA nucleosides, distinguishing them from DNA nucleosides.
  • Deoxyribose

    A five-carbon sugar lacking an oxygen at the 2' position, found in DNA nucleosides and nucleotides.
  • Glycosidic Bond

    A linkage formed between the nitrogen of a base and the anomeric carbon of a sugar in nucleosides.
  • Phosphate Group

    A chemical group added to the 5' carbon of a nucleoside to form a nucleotide.
  • Monophosphate

    A single phosphate group attached to a nucleoside, signifying the nucleotide form.
  • 5' Carbon

    The specific carbon on the sugar where the phosphate group attaches in nucleotide formation.
  • Deoxy Prefix

    A naming modifier indicating the presence of deoxyribose in DNA nucleosides and nucleotides.
  • One-Letter Abbreviation

    A single character code representing each nitrogenous base, used in nucleotide shorthand.
  • Suffix Modifier

    A naming change applied to the base name, such as 'idine' for pyrimidines and 'osine' for purines in nucleosides.
