nucleobase
This term is a specialized technical noun used almost exclusively within the fields of biochemistry, genetics, and molecular biology. It describes the specific nitrogenous bases that pair to form the rungs of the DNA and RNA double helix. Because it refers to a specific chemical structure, it is used in a precise, descriptive manner rather than a figurative one.
In academic writing, it is frequently used in the plural to discuss the set of bases (adenine, guanine, cytosine, and thymine/uracil) that constitute the genetic code. It should not be confused with "nucleotide," which refers to the complete unit consisting of a nucleobase, a sugar, and a phosphate group.
Meanings
Examples
