Eukaryotic vs prokaryotic
Eukaryotic vs. Prokaryotic

  • Location of DNA

    • Nucleus vs. Nucleoid

    • Double membrane or Non membrane-enclosed


Purpose
Purpose

  • Control center of the cell

  • Contains the DNA in the form of chromosomes

  • Structures include: Nuclear Envelope Nucleolus


Nuclear envelope
Nuclear Envelope

  • Encloses the nucleus

  • Double membrane

    • Perforated by pores

  • Nuclear Lamina

    • Provides support


Nuclear pores
Nuclear Pores

  • “Pore Complex”

  • Regulation of what is transported across envelope

    • Proteins, RNA’s, Macromolecules


Nucleolus
Nucleolus

  • Synthesizing of ribosomal RNA (rRNA)

  • Proteins imported from the cytoplasm assemble with rRNA

  • Formation of ribosomes
