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.
