The document discusses using the heat shock method to perform genetic transformation, which involves implanting a segment of DNA from one organism (a jellyfish) into another organism (E. coli bacteria) to make it display the phenotype for that DNA segment. Specifically, it describes an experiment where heat shock was used to genetically transform a piece of DNA from a jellyfish into a sample of E. coli bacteria in order to observe the effects. The heat shock method is one of three ways that genetic transformation can be done to transfer DNA between organisms.
