Document Summary
Organisms comprised of 1 or more types of cells. New cells can only arise from the division of a pre-existing cell. Prokaryote (structurally simple) and eukaryote (structurally more complex) Parts organized with respect to time and space. Fidelity of interactions maintained through control of regulation of. Non-cellular macromolecular packages that can function and reproduce only within living cells. Virion: virus when it"s outside of a cell= small amount of. Virus binds to cell surface via specific proteins and enters cell. Wide host range infection: hijacks cell machinery to synthesize nucleic acids and proteins to assemble new virus particles: lytic: production of virus particles ruptures/kills cells (influenza, non-lytic/integrative: cell survives but with impaired function. Viral dna inserted in host genome dna= provirus. Control movement of materials in/out of cell (pm only) Provide scaffold for biochemical activities (including energy response to external stimuli (pm only) interactions between cells (pm only) transduction) Asymmetrical: inner leaflet and outer leaflet (glycolipids and glycoproteins)
