DNA replication
This 3D animation shows you how DNA is copied by the cell, a process called DNA replication.
We start by seeing the DNA double helix being unzipped to form a replication fork. We then follow DNA polymerase as it copies the DNA in the 5โ to 3โ direction using the existing DNA as a template. The leading strand is constructed in a continuous fashion while the lagging strand is made discontinuously, in a series of short fragments of DNA called Okazaki fragments.
