Document Summary
Class 1: chlamydomonas: a model system: why is chlamydomonas considered a model system, 10 microns in length. Why is that: has a big chloroplast. Eyespot within the chloroplast: senses the light environment and sends signals to the agella in order to swim toward or away from light, nucleus, endoplasmic reticulum, golgi. Protein export to the plasma membrane: mitochondria. If a cell has a chloroplast, it also has a mitochondria: ribosomes. Experimentally identify the proteins required for each function: mutagenesis, intentionally disrupt/ mutate the genome, insertional mutagenesis- where you insert a piece of foreign. Insert the bleomycin gene (an antibiotic) which makes the cell resistant to bleomycin. Three domains from a common ancestor: bacteria, archaea, eukaryotes. Life developed early: the earth is 4. 6 billions years old, stromatolites (3. 5 billion years old) Formed by cyanobacteria: life started on earth 4 billion years ago, life evolved within 600 million years. Stages of prebiotic evolution: what do you need for life to start.
