... Q7. You just replicated 3 nucleotide pairs in a matter of a few minutes. However, the DNA polymerase in bacteria can replicate 2,000 nucleotides per second! The reason that DNA polymerase needs to travel so fast is because a real bacteria cell doesn’t just have 3 nucleotide pairs – it has 5,000,000! ...
