Answer:
Both archaea and eukaryotes possess histone proteins that complex with DNA.
Explanation:
The domain Archaea includes the prokaryotes mostly found in extreme climatic conditions such as hot springs, hydrothermal vents, etc.
The archaeans are prokaryotes like bacteria and do not have membrane-bound organelles and nucleus. However, like eukaryotes, the archaeans have histone proteins.
Histone proteins are the DNA packaging proteins present in eukaryotes. Histones make scaffold to pack the long chains on DNA into chromatin. The presence of histone proteins makes the archaeans similar to the eukaryotes.
