Document Summary
The three things it takes to make life are. Information (genetics provides information about a cell and how it functions)- we need dynamic information: chemistry- need it to keep life, compartments- life is the chemistry of compartments. The miller-urey experiment: chemical experiment that stimulated the conditions thought to be present on earth which tested the chemical origin of life, used water, methane, ammonia and hydrogen to produce cyanide and formaldehyde. Two types of cells on earth: prokaryotic, bacteria, structurally simpler, eukaryotic, protista, fungi, plants, animals, structurally more complex. Viruses: a virus is a non-cellular macromolecular package that can function and reproduce only within living cells, outside of cells, a virus can exist as an inanimate particle- virion, a virion is composed of: Small amount of dna or rna (encoding to a few hundred genes) Fluid-mosaic model of biological membranes: fluid: individual molecules move, mosaic: diverse particle penetrate the lipid layer.
