Each allele of a single gene in a diploid cell during the G1 phase is present as part of a single (double-stranded) molecule. The Drosophila genome is approximately 150 Mb., which means that a single haploid genome (one allele of each gene) would be 150,000,000 base pairs. Recalling that Avogadro's number is 6 x 10^23 (no units; this is a "pure" number), how many diploid Drosophila cells would be needed to have 1 picomole of each allele?
