Study Notes

Micro CW L2

  • Organisms without a nucleus: Lack a nucleus; prokaryotic
  • Organisms with a nucleus: Have a nucleus; eukaryotic
  • Formation of rRNA and proteins: Ribosomes are formed from ribosomal RNA (rRNA) and ribosomal proteins
  • Genetic information transfer from DNA to RNA: DNA carries the genetic code and is transcribed into RNA, which directs protein synthesis
  • Protein synthesis: RNA directs the assembly of amino acids into proteins
  • Ensuring genetic information passage: DNA replication ensures accurate duplication of genetic material
  • Extracellular matrix composed of polysaccharides: A complex matrix surrounding certain cells or organisms
  • Bacterial cell wall component: Peptidoglycan
  • Fungal/Algal cell wall component: Varies and can include polysaccharides
  • Algal cell wall component: Varies, can include polysaccharides
  • Bacterial genetic material transfer: Conjugation, allows direct transfer of DNA
  • Motility components: Flagella, facilitates movement
  • Flagella presence: Can be in tufts, single at both ends or all around surface
  • Bacterial movement direction: Towards or away from stimuli
  • Bacterial movement change: Change in direction in response to stimuli
  • Microorganism communities: Biofilms/surface associated communities
  • Cell drinking: Endocytosis as a means of capturing liquids
  • Macromolecule production process: Anabolism
  • Oxygen-independent process: Anaerobic respiration
  • Enzyme activity interference: Inhibition of cellular processes
  • Active site blockage: A type of enzyme inhibition, preventing substrate binding to the active site, inhibiting the enzyme's function
