Document Summary

Module 1 - the composition and structure of. We start as a fertilized cell that undergoes many cycles of replication. Prokaryotic cells - simple cell with no internal membrane structures, but has a nucleoid, outer casing of cell is made up of a cell wall and membrane. Eukaryotic cells - classification that means cells have a nucleus that contains most of genetic material. 10x more prokaryotic cells then eukaryotic cells in body, that don"t share same genetic heritage. Some are harmful but those are managed by immune system. Streptococcus salivarius inhabits upper respiratory tract and oral cavity. One of first microbes to colonize a germ-free newborn"s oral cavity and gastrointestinal tract. Is harmless, but can be pathogenic if gets inside body. Makes enzymes useful in breakdown of plant materials that we ingest (ex. oat fibre) A cell is a membrane bound structure containing macromolecules. Information encoded in dna is converted to functional products of cells (rnas and eventually proteins)
