1. Why Replication Matters
8 minutesUnderstand why cells must copy their entire genome before dividing. Connect DNA replication to the cell cycle (S phase) and the inheritance of genetic information.

2. The Replication Machinery
12 minutesLearn the roles of helicase, primase, DNA polymerase, SSBs, topoisomerase, and ligase. Understand how they coordinate at the replication fork.
3. Leading vs. Lagging Strand
10 minutesExplore why DNA polymerase 5-prime to 3-prime directionality creates the leading/lagging strand asymmetry. Trace Okazaki fragment synthesis and joining.
4. Fidelity and Error Correction
10 minutesExamine the three layers of replication accuracy: nucleotide selection, proofreading, and mismatch repair. Calculate how each layer improves the overall error rate.
5. Telomeres and the End-Replication Problem
10 minutesInvestigate why linear chromosomes shorten with each replication. Learn how telomerase extends telomeres and connect this to aging, stem cells, and cancer.
