Learning more in the lab

Yesterday I (with the help and direction of my supervisor) prepared my first gel electrophoresis. I have not yet figured out a good way to see where the wells are (since the gel is transparent), so I had to go on the distance from the previous well. After we ran the electrophoresis and put the finished gel through the imaging machine, we discovered that only two of the three PCR chunks worked. My supervisor has a handful of ideas on why the one may have failed, which we will look into more on Tuesday.
