DNA strands on a gel stained with ethidium bromide when viewed under UV radiation, appear as:
Yellow bands
Bright orange bands
Dark red bands
Bright blue bands
To solve this problem, we need to determine how DNA strands stained with ethidium bromide appear under UV radiation.Let's analyze the properties of ethidium bromide:Ethidium bromide is a fluorescent dye commonly used to stain DNA in gel electrophoresis.When exposed to UV light, ethidium bromide intercalated with DNA fluoresces, allowing visualization of DNA bands.The fluorescence emitted by ethidium bromide-stained DNA under UV light is typically bright orange.Therefore, DNA strands on a gel stained with ethidium bromide appear as bright orange bands under UV radiation.This corresponds to Option 2: Bright orange bands.Thus, the correct option is Option 2.
