1. The Nucleus Stephanie Baur Daniel Luna

2. Eukaryotic vs. Prokaryotic Location of DNA – Nucleus vs. Nucleoid – Double membrane or Non membrane-enclosed

3. Purpose Control center of the cell Contains the DNA in the form of chromosomes Structures include: Nuclear Envelope Nucleolus

4. Nuclear Envelope Encloses the nucleus Double membrane – Perforated by pores Nuclear Lamina – Provides support

5. Nuclear Pores “Pore Complex” Regulation of what is transported across envelope – Proteins, RNA’s, Macromolecules

6. Nucleolus Synthesizing of ribosomal RNA (rRNA) Proteins imported from the cytoplasm assemble with rRNA Formation of ribosomes
