Bi-directional
DNA synthesis
DNA replication
typically proceeds in both
directions simultaneously at any particular replicon.
Note that the leading and
lagging strands at
the two replication forks are on opposite physical strands of the dsDNA starting at the Origin
of Replication.
HOMEWORK: The diagram above is
mislabelled: the upper blue strand has two 5'
ends, and the lower two 3' ends. Based on the complete
figure, what is the simplest change to be made in the
labelling of the blue strands that will produce a correct
figure ?
