Question

what is the purpose of a control sample that is known to be from a given species in an edna surveillance for that species?
a. to identify every species found
b. to amplify the dna in small samples
c. to identify samples containing the target dna
d. to produce multiple banding patterns in a gel

Explanation:

A control sample of a known - species in eDNA surveillance is used as a reference. It helps in validating the detection methods and identifying whether the samples collected actually contain the target DNA of the species of interest. It is not for identifying all species (A is wrong), not for amplifying DNA in small samples (B is wrong), and not for producing multiple banding patterns in a gel (D is wrong).

Answer:

C. To identify samples containing the target DNA
