उत्तर
Ethidium bromide is used to detect DNA bands under UV light on the gel after electrophoresis.
Explanation:
Ethidium bromide is a fluorescent dye that intercalates between the bases of DNA strands. When exposed to UV light, it fluoresces, allowing the visualisation of DNA bands that have been separated by gel electrophoresis. This method is widely used in molecular biology to analyze DNA fragment sizes and confirm the presence of DNA after electrophoresis.
