Question

Elution means ?

• A. Separation of DNA fragments on agarose gel
• B. Cutting and extraction of DNA bands from the agarose gel
• C. Making the DNA bands visible under UV radiation
• D. Isolation of alien DNA from the choice organism

Answer 1

The correct option is B Cutting and extraction of DNA bands from the agarose gel

B. Cutting and extraction of DNA bands from the agarose gel.

Solution : Cutting and extraction of DNA is done to separate the DNA from the gel in which it is collected. Water or a low salt buffer is added to break the cation bridge and dislodge the DNA from the gel and elute it.

So the correct answer is " B. Cutting and extraction of DNA bands from the agarose gel."
