Visually compare the intensity of your team’s Plant-DNA sample with the intensity of the 3 kb band on the DNA ladder (see figure posted below). For example, if your Plant- DNA sample closely matches the 3 Kb band, this represents approximately 125 ng of total DNA. Divide the approximate mass (ng) of DNA in your sample by the volume loaded in the gel minus the loading dye added (i.e., 12 – 2 = 10 μL, since you loaded 12 μL from a 24 μL sample that contained 20 μL DNA prep + 4 μL loading dye. What is the DNA concentration of your sample? ______ng/μL

Question
Visually compare the intensity of your team’s Plant-DNA
sample with the intensity of the 3 kb band on the DNA ladder
(see figure posted below). For example, if your Plant-
DNA sample closely matches the 3 Kb band, this represents
approximately 125 ng of total DNA.
Divide the approximate mass (ng) of DNA in your sample by
the volume loaded in the gel minus the loading dye added
(i.e., 12 – 2 = 10 μL, since you loaded 12 μL from a 24 μL
sample that contained 20 μL DNA prep + 4 μL loading dye.
What is the DNA concentration of your sample? ______ng/μL
