Here are some of my notes from my Introductory Microbiology class. It goes over the basic domains of life and has some information on how genetic sequencing actually happens. If you have any questions, leave a comment!

The Bacteria

• Evolution of three domains
  
• Bacterial morphology – very diverse
  
  • These unique features (eg. Flagellum, etc) are used to group/categorize microbes
    
  • There are three major types (which each replicate by binary fission)
    
    • Coccus (round)
    • Bacillus (tube-like, rods)
    • Spiral
• Bacterial replication by binary fission
  
  • Dividing in the centre equally
    
  • Depending on how it happens, you can get different morphologies
    
• Coccus
  

1. Streptococcus – don’t separate, stay joined as they divide
2. Diplococcus – stay in twos
3. Tetrads – divide and stay together in fours
4. Sarcina – divide down longitudinal plane (eight cells, two tetrads that are stacked on top of each other)
5. Staphylococcus – replicate in different planes (random)
