cytozine
Cytozine is a term used in speculative biology and some science fiction to denote a hypothetical cytosine-like molecule employed in discussions of genetic information processing or synthetic biology. It is not a standard chemical name and does not correspond to a recognized compound in major chemical databases, and there is no consensus on its existence in real-world chemistry.
Conceptually, cytozine is described as a pyrimidine-based nucleoside or base related to cytosine. In various narratives,
Applications and implications: In speculative discussions, cytozine serves as a device to explore genetic code expansion,
Relationship to real-world bases: Cytozine is often contrasted with cytosine and with real nucleoside analogs such
