A) The genome of D. melanogaster consists of approximately 1.7x108 base pairs. DNA synthesis occurs at a rate of 30 base pairs per second. In the early embryo, the entire genome is replicated in five minutes. How many bidirectional origins of replication are required to accomplish this?
B) A bacterial genome consists of 1.7x108 base pairs. How long would it take to complete one round of replication?
