If a researcher has a DNA sample with a concentration of 0.2 micrograms per microliter, how many microliters of DNA must be transfered to conduct a 50 microliter reaction if the final concentration should be 2.3 nanograms per microliter

The amount, in microliters, of the DNA that must be transferred to conduct the reaction will be 0.575 microliters

Dilution principle

The problem can be solved by using the dilution equation.

Mathematically, the equation is given as:

m1v1 = m2v2

Where m1 = imitial concentration, m2 = final concentration, v1 = initial volume, and v2 = final volume.

However, the initial and final concentrations, in this case, should first be converted to the same units.

0.2 microgram = 0.2 x [tex]10^{-6}[/tex] grams

2.3 nanograms = 2.3 x [tex]10^{-9}[/tex] grams

Thus, 2.3 nanograms = 2.3 x [tex]10^{-3}[/tex] microgram = 0.0023 microgram

What we are looking for is the initial volume.

v1 = m2v2/m1 = 0.0023 x 50/0.2 = 0.575 microliters
