Question

Researchers want to use eDNA to look for an invasive species in a waterway.

Which of these steps would they be likely to do LAST?
A. Collect samples of water with DNA.
B. Compare DNA samples with a control.
OC. Sort DNA into bands on a gel.
D. Cut DNA intp smaller pieces.

Answer 1

Step-by-step explanation:

B. Compare DNA samples with a control would be the step that researchers would likely do LAST

. Before comparing DNA samples with a control, researchers would need to collect samples of water with DNA, sort DNA into bands on a gel, and cut DNA into smaller pieces. These steps are necessary to extract and isolate the DNA from the water samples, amplify the DNA, and visualize it on a gel. Once these steps are completed, researchers can compare the DNA samples with a control to determine if the invasive species is present in the waterway.
