No "beginning-replication problem" on leading strand?

Replication of the leading strand begins at the origins and from those a continuous strand is produced until meeting replicating fork from another direction or end of the strand. The primer is removed by Okazaki fragment going in the other direction.

Scientific paper on DNA replication & gel electrophoresis

... bp lengths of the newly replicated strand every 1 minute for 6 minutes. Strands that migrated to the top of the gel indicate a stalled replication fork. This was the bulk reaction. -Then used gel-filtration chromatography to remove all unbound proteins and then readded only the 3 proteins that ...
