  • Does a prokaryotic cell have DNA?
    Yes, a prokaryotic cell has DNA, but it is circular and located in the nucleoid.
  • What are the main differences between prokaryotes and eukaryotes?
    Prokaryotes lack a nucleus and have circular DNA, while eukaryotes have a nucleus and linear DNA.
  • Are prokaryotes multicellular or unicellular?
    Prokaryotes are typically unicellular.
  • Which cellular structure do eukaryotic cells have that prokaryotic cells lack?
    Eukaryotic cells have a nucleus and membrane-bound organelles.
  • Which organisms are prokaryotic?
    Bacteria and archaea are prokaryotic organisms.
  • Which group of microbes does not have a true nucleus?
    Prokaryotic microbes do not have a true nucleus.
  • Pili are typically used for which of the following?
    Pili are used for attachment and genetic exchange in bacteria.
  • What makes eukaryotes different from prokaryotes?
    Eukaryotes have a nucleus and membrane-bound organelles, while prokaryotes do not.
  • How is the amount of DNA different between a prokaryote and a eukaryote?
    Eukaryotes have more DNA, organized in linear chromosomes, while prokaryotes have less DNA, organized in a circular chromosome.
  • What is the difference between eukaryotes and prokaryotes?
    Eukaryotes have a nucleus and membrane-bound organelles, while prokaryotes do not.
