BIOL 4004 Lecture Notes - Lecture 4: Golgi Apparatus, Archaea, Membrane Protein
Document Summary
Origin of organelles: this is a similar process to the one that was highlighted on the previous exam. Way back in the day, anaerobic archaeon lost their cell walls. This was the beginning stages of the physical divide between the nucleus and the cytosol: sometimes, the anaerobic archaeon got lucky. Instead of ingesting anaerobic prokaryotes like itself, it would ingest aerobic bacterium. Signal sequences: don"t stress too much about these. I would recommend memorizing some of the easier ones (such as the bigger amino acid repeats) and their functions. #1 memorize the entire sequence exactly, but rather take a look at the colored regions. October 9-11, 2018 (on slide 5) and you"ll probably be ne. Nuclear pore complexes: nucleoporins make up the vast majority. Sca old nucleoporins: layer on top of one another to create something that resembles a tube for passage. Channel proteins: line the central pore (where molecules travel).
