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
