Review Questions

What eukaryotic cytoskeletal protein is FtsZ related to?

Compare and contrast cell division during vegetative growth vs. sporulation Similarities = Z-ring formation by FtsZ

Cells of all kinds, including growing cells of B. subtilis, segregate their chromosomes prior to cytokinesis. What is unique about sporulation in this regard?

True or False

Bacteria are too simple to undergo developmental processes.

Chromosome segregation occurs before cell division during B. subtilis sporulation.

The forespore and the mother cell have a full complement of the genetic material at all times.

? factors are bacterial transcription factors that bind to and direct RNA polymerase to specific promoter sequences on the chromosome.

Define an anti-? factor and an anti-anti-? factor.

Why is the gene encoding Green Fluorescent Protein (GFP) a popular reporter gene?

Indicate the cell in which GFP would be observed if its gene were under the control of (A) Spo0A, (B) a ?F promoter or (C) a ?K promoter.

Why is it important for the forespore and mother cell to communicate during sporulation?

What do B. subtlis ?K and the human protein SREBP have in common?
