Study Notes

Taxonomy and Classification

  • Taxonomy is the science of classifying organisms to establish their relationships.

Writing Scientific Names

  • Use binomial nomenclature to write scientific names.
  • Genus name is capitalized and species name is lowercased, both italicized (e.g., Escherichia coli).

Three Domains of Life

Eukarya

  • Organisms with cells containing a nucleus and organelles.
  • Examples: plants, animals, fungi.

Prokarya

Bacteria

  • Unicellular prokaryotes with peptidoglycan in their cell walls.

Archaea

  • Prokaryotes lacking peptidoglycan.
  • Often living in extreme environments.

Diagnostic Techniques

ELISA (Enzyme-Linked Immunosorbent Assay)

  • Used to detect and quantify substances such as proteins, peptides, antibodies, and hormones.

PCR (Polymerase Chain Reaction)

  • Amplifies DNA sequences to make them easier to study.

Western Blot

  • Protein analysis method that detects specific proteins in a sample using antibody binding.

Taxonomy

  • Taxonomy is the science of classifying organisms to establish their relationships.

Three Domains of Life

  • Eukarya: Organisms with cells containing a nucleus and organelles, including:
  • Plants
  • Animals
  • Fungi

Prokarya

  • Prokarya consists of two sub-domains:
  • Bacteria: Unicellular prokaryotes with peptidoglycan in their cell walls.
  • Archaea: Prokaryotes lacking peptidoglycan, often living in extreme environments.

This quiz covers the basics of taxonomy, scientific naming conventions, and the three domains of life: Eukarya, Prokarya, and Archaea.
