  1. Define taxonomy and understand the scientific way of writing names of organisms (binomial system). Methods in Microbiology (CO1)
  2. Overview of methods used in Microbiology- Understand and explain the five I’s
  3. Know and understand the parts of microscope and their functions.(specifically objective and ocular lens
  4. Electron microscopes used for what
  5. Understand the principle of staining, types of stains/ dyes (mainly differential staining)
  6. Compare and contrast types of staining with their application - simple, differential (Gram, acid fast, endospore), and special staining (flagellar, negative/ capsule).
  7. Know the different types of growth media- solid, semisolid and liquid. Describe purpose and original source of agar.
  8. Understand the different types of media based on function- selective and differential media Genetics and genome (CO2)
  9. Understand the structure and function of DNA and RNA, types of RNA (m-, r-, and t- RNA) and their function, the nitrogenous bases- A,T,C,G, and U; sugars: deoxyribose and ribose.
  10. Understand the central dogma of life- know what happens in replication, transcription and translation. Be able to start with a strand of DNA and make complimentary DNA stand, a mRNA and given the amino acid table translate the fragment into protein.
