This week in lab, we ran our plant DNA that we extracted last week from Erythranthe guttata samples through a gel electrophoresis process.

We aloquoted 2-microliter drops of loading dye onto a piece of parafilm. Then, we added 3-4 microliters of our extracted DNA samples.  The entire solution was added to the gel cells, along with the other samples and a ladder in the final cell.  These samples were run in the gel for the remaining lecture (about an hour).
