DNA synthesis of lagging strand, animation

Videonummer 11938981
Animation showing the synthesis of the lagging strand of DNA (deoxyribonucleic acid) during replication. The lagging strand is synthesised in small segments, known as Okazaki fragments, rather than in a continuous process as on the leading strand. The process is started by DNA primase (red), which adds a short RNA (ribonucleic acid) primer (blue) to the strand to be synthesised. DNA polymerase III (white) then attaches to the primer and synthesises a new DNA strand from the template strand (bottom). When DNA polymerase III meets another RNA primer it detaches from the DNA. DNA polymerase I (green) then attaches and removes the RNA primer and replaces it with DNA. The gaps between the Okazaki fragments are then joined by DNA ligase (pink).
