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
