The theory of the archaeal origin of the eukaryotic cell is supported by several components of the modern eukaryotic cell. Here are some of them:

1. Genetic Similarities: The genetic material of eukaryotes is more similar to Archaea than to Bacteria. This is based on the comparison of ribosomal RNA sequences, which are used as a molecular clock to determine evolutionary relationships.

2. Transcription and Translation Machinery: The machinery for transcription and translation in eukaryotes is more similar to that of Archaea. For example, both eukaryotes and Archaea have multiple RNA polymerases, a feature not found in Bacteria.

3. Membrane Lipids: The membrane lipids of Archaea and eukaryotes are isoprenoids, which are ether-linked to glycerol. This is in contrast to Bacteria, which have ester-linked fatty acids.

4. Histones: Archaea and eukaryotes both have histones, proteins that help package DNA into a compact, organized form. Bacteria do not have histones.

5. Introns: Both Archaea and eukaryotes have introns in their genes, which are sequences that are transcribed into RNA but are not translated into protein. Bacteria do not have introns.

These similarities suggest that eukaryotes and Archaea share a common ancestor, supporting the theory of the archaeal origin of the eukaryotic cell.
