  3. Taxonomy

    The grouping of species based on common ancestry
  4. 3 Domains

  6. Genome

    The complete genetic makeup of an organism
  7. Genomics

    Techniques used to analyze DNA sequences in genomes
  8. Proteomics
    Techniques used to analyze the proteome of a single species and the comparison of proteomes of different species
  9. Proteomes

    • The complete complement of proteins that a cell or organism can make
    • The genome carries the information to make its proteome
  10. Science

    The observation, identification, experimental investigation, and theoretical explanation of natural phenomena
  11. Hypothesis

    • Proposed explanation for a natural phenomenon
    • Educated guess based on previous observations or experimental studies
    • A hypothesis is never really proven
  12. Theory

    • Broad explanation of some aspect of the natural world that is substantiated by a large body of evidence
    • Allows us to make many predictions
    • Also can never be proved true
    • Example:The theory that DNA is the genetic material
