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
