Upon exposure to UV radiation, DNA stained with ethidium bromide will show:
Bright red colour
Bright blue colour
Bright yellow colour
Bright orange colour
To solve this problem, we need to understand the interaction between DNA, ethidium bromide, and UV radiation.Ethidium bromide is a fluorescent dye that intercalates between the bases of DNA.When exposed to UV light, ethidium bromide emits fluorescence.The fluorescence emitted by ethidium bromide when bound to DNA is typically an orange color.Therefore, upon exposure to UV radiation, DNA stained with ethidium bromide will show a bright orange color.This corresponds to Option 4: Bright orange colour.
