BIOL 110H Lecture Notes - Lecture 4: Eukaryote
Document Summary
Bio110h- lecture 4- eukaryotic cells: subcellular organization and information flow. Conjugation of a plasmid- can either move into another cell (via a pilus) and reform into a circular plasmid; or can integrate into the nuclear genome. Cells with plasmids replicate slower than those without this is because there is more genetic information to replicate. Cells infected by m13 virus grow slower due to the excessive genetic. Genetic exchange mechanisms were helpful with understanding genetics information from the virus. Classified by rrna sequences (we look at the dna translated from them) protein synthesis in the tree, branch connections show ancestry, and trace all three classifications back to a common ancestor. Endosymbiosis- cyanobacteria chloroplasts in plants; mitochondria (not in bacteria) engulfed by bacterial cells as a bacterial cell and create eukaryotes. Chemoautotroph- derives its carbon from carbon dioxide, and gets its energy from chemicals (deep sea organisms) Photoautotrophs- plants (derive carbon from co , and get energy from light)
