DNA replicаtiоn in eаrly Drоsоphilа embryos occurs about every 5 minutes. The Drosophila genome contains approximately 1.8 X 108 base pairs. Drosophila DNApolymerases synthesize DNA at a rate of approximately 40 nucleotides per second. How many origins of replication are required for this rate of replication?
