BIO206H5 Final: bio206 lec notes
Document Summary
1 cell division occurs until they run out of food and then starve to death + as they increase they release toxins that cause illnesses. Central dogma of molecular bio: replication (dna synthesis, transcription (rna synthesis, translation (protein synthesis) Molecular bio: interactions bw various systems of a cell, including interrelationship od dna, rna, protein synthesis and protein trafficking + how all these interactions were regulated. Cell theory: cell=smallest unit of life, all living things made of cells, new cells arise from preexisting cells (consequence of success in reproduction) Cell: fundamental unit of life, liquid membrane bound unit filled with [] aq solution containing. 2 classifications of cell (major: prokaryotes (cell with no defined nucleus) Plasma membrane, cell wall, cytoplasm, nucleoid, ribosomes, internal membrane: eukaryotes (cell with true nucleus) flagella. Nucleus, er, golgi apparatus, vesicles, peroxisomes, mitochondria, membrane, cell wall + cytosol ( [] aq gel, ribosomes, cytoskeleton) 2: nucleotide sequence encoding of 16s or 18s rrna.
