Lecture 3 Prokaryotic Cell Biology Part I
1) How does the arrangement of DNA differ between prokaryotes and
eukaryotes?
2) What is coupled transcription-translation, and why does it happen only in
prokaryotes? What’s a benefit to coupling these two processes?
3) What types of things are stored in cytoplasmic inclusion bodies? How would
you expect growth state affect whether some inclusion bodies are found?
4) Describe the cytoplasmic membrane structure of Bacteria, and how this differs
in Archaea and Eukaryotes.
5) What are the two main sugars of the Bacterial cell wall? Are these sugars
found in Archaeal or Eukaryotic cell walls?
6) What are some distinguishing features of Gram negative and Gram positive
bacteria?
7) What is the function of the cell wall? What happens if you remove it? Does it
matter what solution the prokaryote is in when you remove it? Why?
8) How do penicillin and lysozyme affect the cell wall? What is the molecular
basis for this?
9) How do gas vesicles allow prokaryotes to move? What kinds of gases are in
these vesicles?
10) How do magnetosomes benefit prokaryotes? How do these "work"?
