Q

How do bacterial features compare with eukaryotic?

A

Genome
* Bacteria: Usually circular DNA, one chromosome, and lacks introns.

  • Eukaryote: Linear DNA; multiple chromosomes, in pairs; may have introns.

Location of DNA
* Bacteria: Nucleoid region in cytoplasm.

  • Eukaryote: Contained within membrane-enclosed nucleus.

Cell wall
* Bacteria: Usually present, composed of peptidoglycan.

  • Eukaryote: If present, composed of cellulose (algae) or chitin (fungi).

Internal membranes
* Bacteria: May have energy-transduction lamellae.

  • Eukaryote: Extensive membranous organelles.
