Protocol notes

DNA Extraction: No errors made. Changed pipette tips between each sample.

PCR: Pipette tip still held a bit of DNA solution after depositing 2 uL into the B-3 0.2 mL PCR Tube.

Gel electrophoresis, Arthropod CO1: In Lane 1 is a DNA Ladder, in Lane 2 is Sample #1, in Lane 3 is Sample #2, in Lane 4 is Sample #3, in Lane 5 is Sample #4, in Lane 6 is a Positive Wolbachia Control, in Lane 7 is a Negative Wolbachia Control, and in Lane 8 is Water. No errors were made during this procedure and controls worked as intended.

Gel electrophoresis, Wolbachia: In Lane 1 is a DNA Ladder, in Lane 2 is Sample #1, in Lane 3 is Sample #2, in Lane 4 is Sample #3, in Lane 5 is Sample #4, in Lane 6 is a Positive Wolbachia Control, in Lane 7 is a Negative Wolbachia Control, and in Lane 8 is Water. No errors were made during this procedure and controls worked as intended.

Results
Wolbachia presence No
Confidence level High
Explanation of confidence level

No mistakes were made during our gel electrophoresis and the controls for our Wolbachia and Arthropod CO1 gels were consistent with expected results, giving our sample results confidence.
