The Nucleus Stephanie Baur Daniel Luna

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

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

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

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

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