Protocol notes

STEPS OF ISOLATION:

•Prepare sample

•Cell lysis and DNA precipitation

•DNA Purification

DNA Elution

STEPS OF PCR:

•PCR

•Purpose/ Goal: The purpose of PCR is to amplify a specific DNA segment

•It is essential in identifying an organism and identifying infection

•Process:

•Denaturation

•DNA is heated which separates the double-stranded DNA into single strands by breaking hydrogen bonds

•Temperature: 94 – 96 °C

•Annealing

•allow primers to bind (anneal) to their complementary sequences on the single-stranded DNA

•Temperature: 49-55 °C

•Elongation

•Synthesizes new DNA strands as Taq polymerase adds nucleotides to the primers

Temperature: 72 ° C

Results
Wolbachia presence No
Confidence level Low
Explanation of confidence level

Gel electrophoresis was unsuccessful as the pipette tip was penetrated the gel, therefore I was unable to determine Wolbachia presence
Wolbachia 16S sequence

Summary The Harmonia axyridis was found to be negative for Wolbachia.
