Archea is considered as a separate group from bacteria and eukaryotes, based on
Mechanistically, microbial physiology involves growth regulation and host interactions follow molecular programs. This validates 16S rRNA gene sequence. because it corresponds to prokaryotic strategies, a pattern repeatedly demonstrated in microbiology research.
Ref: Madigan et al., Brock Biology of Microorganisms, 15th Edition, Chapter 13, Virology, explains viral replication and virus-host interactions detailing microbial genetics.
