Here are some key traits that distinguish the three domains of life (some of which are from the table on IB chapter 3.2). Consider the tree below showing the relationship of the three domains. Characteristics Nuclear envelope Organelles Peptidoglycan in cell wall Membrane lipids RNA polymerase Ribosome Initiator amino acid for protein synthesis Introns in genes Histones associated with DNA Circular chromosome Operons Plasmids Bacteria Archaea 1 2 LUCA Bacteria No No (rare) Yes Unbranched hydrocarbons Ester linked Version 1 70S Formyl- methionine Very rare No Yes Yes Yes Binary fission Sensitive Reproduction Response to antibiotics streptomycin and chloramphenicol Response to diptheria toxin Think through how you would map all of these characteristics onto this tree.

Here are some key traits that distinguish the three domains of life (some of which are from the table on IB chapter 3.2). Consider the tree below showing the relationship of the three domains. 7 Characteristics J Nuclear envelope Organelles Peptidoglycan in cell wall Membrane lipids RNA polymerase Ribosome Initiator amino acid for protein synthesis Introns in genes Histones associated with DNA Circular chromosome Operons Plasmids Bacterial Archaea 1 2 Bacteria LUCA No No (rare) Yes Unbranched hydrocarbons Ester linked Version 1 70S Formyl- methionine Very rare Reproduction Response to antibiotics streptomycin and chloramphenicol Response to diptheria toxin Think through how you would map all of these characteristics onto this tree. No Yes Yes Yes Binary fission Sensitive Not sensitive 5 a) Which characters might fall at location 1? No No No Some branched c) Which characters would fall at location 3? Domain Archaea hydrocarbons.
