Loading a gel with DNA samples - at least I'm hoping there's DNA in them.
DNA is negatively charged, and by applying electricity to the gel, the top end becomes negative and the bottom becomes positive. Opposites attract: the DNA will move towards the bottom.
I have little wells to slot my samples in so that they line up nicely, and I've coloured them blue so that I can actually see them go in.
This gel is filled with grooves and tunnels. The shorter the DNA, the quicker it can weave through the gel, so all the DNA is separated by size. If the DNA I want is present, it'll separate out.
Fingers crossed for DNA!
