Problem:
DNA replication in early Drosophila embryos occurs about every 5 minutes. The Drosophila genome contains approximately 1.8 X 108 base pairs. Eukaryotic DNA polymerases synthesize DNA at a rate of approximately 40 nucleotides per second.
Required:
Question: How many origins of replication are required for this rate or replication?
Does anybody know any source of this kind?
