DNA REPLICATION Replication: The process of copying DNA prior
... Scaling this up, the speed of polymerase would be equivalent to 375 miles per hour. Polymerase in humans works at a much slower rate—around 50 nucleotides per second. Because eukaryote DNA has multiple replication sites (bubbles), copying the entire genome only takes the cell about an hour. Polymera ...
