Eukaryotic vs. Prokaryotic

• Location of DNA– Nucleus vs. Nucleoid– Double membrane or Non membrane-

enclosed

Page 3: 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
