Using your knowledge of the proteins involved in the process of
DNA replication, and their requirements for activity, please add to
or re-draw each of the following DNA diagrams as would be needed to
account for the effect of adding only DNA pol I and
dNTPs to each DNA molecule. Please briefly explain the
rationale for each diagram. (Note: Each circular or linear line
represents a single strand of DNA or RNA. See legend below)
