Answer:
Isolate DNA from all organisms and store at --20ºC.
Explanation:
The first step to be taken, in the case shown in the question above, is to isolate DNA from organisms, as molecular assays will need to be performed and these assays require the presence of the organism's DNA to be performed. Because DNA is a sensitive and unstable molecule, it must be preserved in a refrigerated environment to maintain its integrity and to be studied. Then, after isolating the DNA, technicians must store the DNA in refrigeration. It is best to store the DNA at -20ºC.
