1. Prokaryotic Genomes

2. Prokaryote Diversity Bacteria species are everywhere! Due to:
Billions of years of existence
Large populations
Short generations
Rare, but regular mutations

3. Prokaryote Diversity

4. Prokaryote Characteristics
Size: 0.5-5µm
Genome:
Singular chromosome (primary DNA)
Many plasmids: small circular DNA (secondary DNA)
No membrane-bound organelles
Cell wall & membrane
Cytoplasm
Nucleoid region
Ribosomes
Flagellum

5. Prokaryote Shapes Common Shapes Spherical: cocci Rod-shaped: bacilli
Spiral: spirilla

6. Prokaryote Reproduction
Rapid Asexual Reproduction
Binary Fission

7. Prokaryote Replication
