(Note: Each linear line represents a single strand of DNA.) (a) Annotate the diagram (inside each fork) so that it accurately shows the result of nucleotide polymerization through the action of the replisome, prior to any activity by DNA Pol I and DNA ligase. Be sure to label the polarity of all DNA polymers! (Note: you don’t need to draw the replisome proteins. Just draw the DNA that is made.) (4 marks) (b) Add DnaB to the diagram to show where it would bind and its direction of movement if ATP were added to this protein-DNA complex.
