A nucleoside is formed when a nitrogenous base is linked to a sugar. What is the resulting structure when a phosphate group is also attached to the nucleoside?
Show answer and explanation
Correct answer: Nucleotide
A nucleotide consists of a nitrogenous base, a pentose sugar, and a phosphate group. A nucleoside lacks the phosphate group. Linking many nucleotides produces a polynucleotide chain, and nucleic acids are formed from such chains.
