The Lagging Strand and Okazaki Fragments
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
The lagging strand is synthesized discontinuously, in short Okazaki fragments, each started by its own primer pointing away from the replication fork.
Show
As the fork opens further, a new primer and Okazaki fragment begin, repeating for the strand's length.
Watch for
Okazaki fragments still extend 5' to 3', obeying Bio 1221's rule — only their direction along the strand runs opposite the fork.
