2. assuming that there were no time constraints on replication of the genome of a human cell, what would be the minimum number of origins that would be required? if replication had to be accomplished in an 8-hour s phase and replication forks moved at 50 nucleotides/second, what would be the minimum number of origins required to replicate the human genome? (the human genome has a total of 6.4x 109 nucleotides)
