What is the Linnean classification scheme? How do we currently organize (or classify) organisms using this method?
Hierarchical classification: Based on similarities in obvious physical traits
-Species(genus)>family>order>class>phylum>kingdom>domain
What are the defining features of the prokaryotes? What characteristics unite the bacteria and archaea? What characteristics allow you to differentiate between them? What characteristics indicate that bacteria and archaea are distinctly different domains?
Prokaryotes: single-celled organisms lacking a nucleus with a single piece of DNA in the cell nucleoid area.
Archaea V. Bacteria
Characteristic, Bacteria, Archaea
Characteristic: nuclear envelope, membrane-enclosed organelles, peptidoglycan in cell wall, membrane lipids, RNA polymerous, initiator amino acid for protein synthesis, Introns in genes, response to the antibiotic's streptomycin and chloramphenicol, histones associated with DNA
