27. Jennifer ordered the primers for the PCR reaction and received dried oligos in the tubes. She got 30 nanomoles (nmol) oligos of the forward primer, and 25 nanomoles (nmol) oligos of the reverse primer. She would like to the prepare stock solution in 100 nM. How much water should be added into the tubes to make the stock solutions for these primers? (A)300 µl for the forward primer, 250 µl for the reverse primer (B) 30 µl for the forward primer, 25 µl for the reverse primer (C) 3 ml for the forward primer, 2.5 ml for the reverse primer (D)3 µl for the forward primer, 2.5 µl for the reverse primer (E) 30 ml for the forward primer, 25 ml for the reverse primer
