What is the main role of restriction enzymes in the analysis of eDNA? O A. To break DNA into various-sized fragments that can be sorted and
analyzed
B. To purify samples of DNA obtained from the environment so that
they can be analyzed
O c. To sort various-sized DNA fragments into a banding pattern that
can be analyzed
O D. To amplify small amounts of DNA by generating large amounts of
DNA that can be analyzed

B

Explanation:

The natural role of the restriction enzymes is to protect the cell from invading phages. The restriction enzyme is an enzyme that functions by cutting DNAs from some pre-identified sites on the DNA. They are primarily found in bacteria where they protect the cell from invasion by foreign DNA from phages.
