  3. Conjugation Pili • Pass DNA to buddies

  4. Plasmid

  5. The nucleus and ribosomes • Today discuss: what is in the nucleus • What is made in the nucleus • What is a ribosome? What does it do?

  6. Questions p. 70 • What is the difference between chromatin and chromosomes? • What is a nuclear pore?

  7. Questions p 71 • What is a ribosome? • What makes up a ribosome?

  8. Inside the nucleus • Nucleolus – makes rRNA • Chromatin and Chromosomes • Chromatin – thin DNA stretched out • Chromosomes = dense chromatin

  9. Ribosomes • Made up of rRNA • Protein Synthesis

  10. Ribosomesoccur in cytoplasm by themselves • Or Hangout with Endoplasmic Reticulum (ER) • Ribosome binds with ER when it is told to • ER helps with protein folding – requires a SRP (signal recognition peptide)
