Are bacteria and viruses eukaryotes or prokaryotes? What does this term mean?
Bacteria and viruses are prokaryotes. Prokaryotes are organisms which lack organelles and membrane bound nuclei
How do bacteria reproduce
Bacteria reproduce via binary fusion (asexual division)
Describe the structure of a virus
Genetic material (DNA or RNA), surrounded by a protective layer of protein and sometimes lipid and carbohydrates
What are the 5 types of virulence factors and what are they’re functions
Adhesins (bidning of organism to host), Invasins (enables orgasms to invade/enter cell), impedins (avoids hosts defence mechanisms), agressin (causes damage to host) and modulins (induces damage to host indirectly)
