Base pairing · helicase · polymerase · semiconservative replication

Learning outcomeBuild complementary DNA strands while following the direction and rules of replication.

Learning challenge

DNA segment length2400 bpPolymerase rate200 bp/sReplication forks2

Replication time6.0 s

Total throughput400 bp/s

ModelBidirectional forks

Learning focus

See how replication speed and multiple forks change the time needed to copy DNA.

replication time ≈ length / (rate × active forks)
