DNA replication in Drosophila embryos is known to happen about every 6 minutes. The Drosophila genome is composed of approximately 1.8 x 108 base pairs. If Drosophila DNA polymerases synthesize DNA strands at a rate of approximately 40 nucleotides per second, how many origins of replication would be required for... show more DNA replication in Drosophila embryos is known to happen about every 6 minutes.
