Why is safety important while choosing DNA stain?

Answer and explanation

Correct answer: Some DNA stains can be mutagenic or hazardous

Some stains used to visualize DNA, such as ethidium bromide, can be mutagenic and may pose health or environmental risks. Therefore, toxicity, safe handling, PPE, and proper disposal must be considered when selecting a stain. Option D is incorrect because not all stains are non-toxic. Exam tip: For DNA-stain safety questions, remember mutagenicity and waste disposal.
