Answer 1

Archaean biochemistry is more similar to that of eukaryotes than that of eubacteria. if that was the option that should be the one

Answer 2

Archaean biochemistry is more similar to that of eukaryotes.

Step-by-step explanation:

Both eubacteria (true bacteria) and archaea constitute unicellular, prokaryotic microorganisms, in which nucleus and other membrane-bound organelles are absent.

However, archaea share more similarities with eukaryotes as compare to bacteria. For example, most of genes involved in gene expression (in transcription and translation) are common between archaea and eukaryotes, while different in eubacteria.

Thus, the correct answer is option). 'archaean biochemistry is more similar to that of eukaryotes.'
