You are given 10ml of a DNA stock solution that has 1.0mg target DNA/mL. The target DNA molecule is 2.9kb in length. Describe a set os serial dilutions that would yield a standard curve with the following concentrations: 2X10^7 copies/mL, 2X10^6 copies/mL, 2S10^5 copies/mL, 2X10^4 copies/mL. Make all of dilutions in water, and do NOT pipet less than 10mL. You may use as many tubes as you want for making dilutions.
