This fact sheet is for the video DNA replication: How does a cell make a copy of its DNA?
Have you ever wondered how DNA is accurately copied in cells and why pregnancy in humans doesn't last sixteen years?
This video breaks down the intricate steps of DNA replication, from unwinding the double helix to overcoming twisting events. The video covers how the enzyme DNA helicase unwinds the DNA, the formation of the replication fork, how the polymerases make a copy of the DNA, how and why Okazaki fragments are generated and how these are joined together by DNA ligase. The role of topoisomerase in solving the winding problem is also discussed.
