I. Compare how Bacteria, Archaea, and Eukaryotes differ on each of the following aspects of
DNA replication:
1. How do the number and types of DNA polymerase differ between these three groups?
2. How does the physical location in the cell of DNA replication differ between these three
groups?
3. Are there differences between these three groups in the timing of when DNA replication
occurs in cells?
4. How does origin of replication differ in terms of number and location between these three
groups?
Application/ Analysis
Explain how the anti-parallel structure of DNA predicts its replication mechanism.
Identify the major and minor groove of DNA and explain why they are there.
Differentiate between semiconservative, conservative, and dispersive replication.
Interpret a diagram of a bi-directional replication fork and correctly determine strand polarity and fork direction.
Preforming a "blue-white screen"
3) Would bacteria that have taken up a plasmid into which a DNA fragment has been inserted, form a blue colony or a white colony when grown on this medium? Briefly explain why these bacteria would form a colony of the color you chose.
