Document Summary
Biol 130 intro to cell biology: unit 1. Cell biology + microscopy - history of cell biology is embedded in microscopy. Worked w/ glass lens (~300x magnification), 1st to sketch images. First observed single-celled protists, bacteria, diarrhea + sperm. Allowed visualization of objects < 1 micrometer. Plant cell has round structure nucleus. Formulated cell theory all consist of 1 or more cells. (20 yrs later) arise from pre-existing cells. Highly complex + organized atoms molecules macromolecules organelles enclosed in membrane. Central dogma dna replication, transcription and translation (term coined by francis crick) Bioenergetics making of atp and other chemical rxns. Mechanical activities moving in/out of cell; some can move on its own. Stimulus response respond to hormone, bind to receptor . Many cellular processes are highly conserved at the molecular level; similar processes occur by similar genes strand. Prokaryote - pro = before, karyon = nucleus. Eubacteria all have cell wall except mycoplasma (smallest)
