Document Summary

Week 1: introduction to cells, diversity, and nucleic acids. Provide knowledge and preparation for 2nd, 3rd, and 4th year courses in csb and related disciplines. Examine some highlights of the biological revolution underway. Discover some connections between basic molecular and cell biology research and its application in our lives. Prokaryotes and eukaryotes: differences and similarities, general organization, origins. Transparent, can see what happens to each cell. General concepts about dna, rna, and proteins: nomenclature o o. Nuclear and organellar genomes: organelles have their own dna genomes (mitochondria and chloroplast) Basic tenets of cell theory: all organisms are comprised of one or more cells. 2: all cells arise from pre-existing cells. The cell is the basic organizational unit of life. Prokaryotic cells: pro = before, karyon = nucleus. Eukaryotic cells: eu = true, karyon = nucleus. Genetic material in nucleoid, lacking boundary membrane to separate from cytoplasm. Seem to live in biofilms, complex, multispecies communities (e. g. , plaque)
