Question

Researchers want to use edna to look for an invasive species in a waterway. which of these steps should they do last? a. precipitate dna in each sample. b. sort dna into bands on a gel. c. cut dna into small pieces. d. amplify the amount of dna.

​

Answer 1

The step at which the researchers would do at the end of researching Edna is to amplify the amount of DNA.

Option (d);

Step-by-step explanation:

• The term EDNA means Environmental DNA.
• Invasive species in the waterway are the waterborne plants and animals who can likely cause effects to the human as well as the environment.
• If researchers want to use eDNA to look for invasive species in the waterway, they will first collect a sample.
• After cutting DNA into pieces, DNA would be precipitated in each sample.
• And in the end, the amount of DNA would be amplified in each sample to understand how it would cause harm to the environment.
