What are nucleic acids and what are they composed of?
Nucleic acids are large molecules formed by the repetition of a unit molecule called a nucleotide. Nucleotides are composed of a pentose sugar, a phosphate group, and a nitrogenous base. There are two types of nucleic acids: DNA and RNA, which differ in the type of sugar they contain and the nitrogenous bases they have.
