Assertion: The separated DNA fragments can be visualized only after staining the DNA with a compound known as ethidium bromide followed by exposure to UV radiation.
Reason: We can see bright red coloured bands of DNA in an ethidium bromide-stained gel exposed to UV light.
Answer:
The correct option is (a) Both assertion and reason are correct.
Explanation:
Separation of DNA fragments is typically performed by gel electrophoresis. In this technique, DNA fragments are loaded onto a gel matrix and subjected to an electric field. The electric field causes the DNA fragments to migrate through the gel matrix and separate based on their size.
However, these separated DNA fragments are not visible to the naked eye. To visualize them, the gel is stained with a compound known as ethidium bromide, which intercalates between the DNA fragments and fluoresces under UV radiation.
Therefore, the reason given for the assertion is correct. Ethidium bromide-stained gels exposed to UV light appear as bright red coloured bands of DNA, with each band representing a different-sized DNA fragment.
Hence, both the assertion and reason are correct.
