DNA and RNA are 2 types of nucleic acids that have different staining properties. DNA is acidic and stains acidic dyes, while RNA, along with proteins, stains basic dyes. The 2 stains used are methyl green and pyronine. DNA stains blue or bluish-green with methyl green, and RNA stains pink with pyronine dyes. DNA is present in the nucleus and stains blue or bluish-green, while RNA is present in the cytoplasm and stains pink.
DNA (nucleus) stain blue and RNA (cytoplasm) stain pink.
