That looks like hair!

The DNA Sequencer is located in the Sickbay on the SCS Deepship 86. Occasionally used for analyzing organisms and artifacts discovered, but more often used to make sure the food replicators are working properly. According to a StarCon regulation, only trained personnel are authorized to use the Sequencer, however on one occasion, Jebba the Hop let Roger use it to analyze Nigel's hair.
