Question

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)

Answer 1

46 origins

Step-by-step explanation:

there were no time constraints on replication, one origin would be required for each chromosome; thus, a minimum of 46 origins, equal to the number of chromosomes in a human cell, would be needed.
