The given cell belongs to domain Archaea.
The Archaea known as ancient bacteria exhibit DNA wrapped around histones to produce chromatin. Eubacteria do not compose of histones. Eukaryotes have multiple linear chromosomes, while Archaea have a single circular chromosome.
Archaea are the microbes and are prokaryotes, which means that they are devoid of the cell nucleus. These species exhibit different molecular features distinguishing them from bacteria as well as from eukaryotes.
