Bacteria + Archea Cells in all 3 domains share characteristics Basic Building Blocks Genetic Info Flow Flow of genetic info from DNA to RNA (through the process of transcription) which produces protein (using translation machinery) DNA -> RNA -> Protein Plasma Membrane Selectively permeable membrane separates inside of the cell from the external environment has protein complex's in it that allow for the controlled transport of materials into and outside the cell Use and need for energy (energy metabolism) serial = stages Schloroplast - cyanobacterium protein is made in cytoplasm mitochonda - alpha-proteobacteria nuclear laminia rRNA assembled w/in Nucleolus Nuclear DNA exists as chromatin DNA plus associated proteins. (histone and non-histone proteins) Nucleus .chromosome Histones Nuclear Evelope Allow DNA to fit in nucleus Continuous w/ ER Nuclear pore complex (NPC) •They allow for entry and exit of materials
