The speed of DNA replication at a replication fork is about 100 nucleotides per second per standin human cells. What is the minimum number of origins of replication that a human cell must have in order to replicate its DNA once every 24 hours? Recall that a human cell contains two copies of the human genome, one inherited from the mother and one from the father, each consisting of 3 x 109base pairs.
