FIG. 4.
Unwinding of the nascent leading and lagging strands of the replication fork by StoHjm. A replication fork containing a labeled leading strand (S11) (A) or a labeled lagging strand (S10) (B) was used as a substrate. (C) Quantification of the results in panels A and B. Percent unwinding was calculated as the ratio of unwound DNA (total DNA substrate minus the remaining substrate) to total labeled DNA. The lengths of the DNA strands (in nucleotides) are labeled.
