BSC 1010 Lecture Notes - Lecture 5: Heredity, Systems Biology, Emergence
Document Summary
Emergent properties sum of the parts is greater than the parts sum reductionism reducing a complex system to the sum of its parts to make it more manageable ex. Watson-crick studying molecular structure of dna and inferring the chemical basis of biological inheritance systems biology put the reduced elements in the context of a whole ex. tissue and organ systems. Hierarchy of biology molecule, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem. Structure and function are coupled across resolutions ex. appendages, cells, organs, organelles, molecules heritable info in dna heritable info in dna is found in it"s sequence and structure helical model. Atcg in a water molecule, which is partially negative oxygen. 2 fatty acid on gylcerol and phosphate group on the 3rd hydroxyl (oh) saturated fat no double bonds; solid at room temp unsaturated fat double bonds; liquid at room temp similarities between prokaryotic and eukaryotic cells. Motility proteins on membrane differences between prokaryotic and eukaryotic cells.
