Document Summary

Chapter 26 phylogeny and the tree of life. Shared characters are used to construct phylogenetic trees: cladistics. Structural and functional adaptations contribute to prokaryotic success: cell-surface structures, cell wall maintains cell shape, protects cell, prevents cell from bursting in hypotonic environment. 3: reproduction, prokaryotes reproduce via binary fission with short generation times. Dna into recipient cells dna: conjugation in plasmids, conjugation: dna transferred between 2 prokaryotic cells that are temporarily joined one-way transfer, pilus of donor attaches to recipient, and pulls cells together. Mating bridge between cells allows for dna transfer. Is possible due to f factor, f plasmid, and r plasmid. Chemoheteroproph organic compounds organic compounds pro. , protists, fungi, animals, Inorganic chemicals co2, hco3-, etc unique to certain pro. Initiator a. a. in protein synthesis formal-methionine methionine methionine. 5: prokaryotes radiated into diverse set of lineages due to differences in, cell wall components, rna polymerase, translation chemicals, histones, introns.
