I actually thought about it when coming up with the Plasmid. The answer is yes.

Also, there aren't just twelve Plasmids. The ones you see on the main section are just the basic Plasmids. Click on their links and you'll see their combos (i.e. Plasmids you can make by combining two basic ones). So, in total there are 78 Plasmids to choose from.
