Which staining method uses two dyes to differentiate DNA and RNA, with DNA stained blue-green and RNA pink-red?

Explanation:
Differentiating DNA and RNA with two dyes is achieved using methyl green-pyronin staining. Methyl green has a strong affinity for DNA and stains it blue-green, typically giving the nuclei a blue-green hue. Pyronin Y binds RNA more avidly, staining RNA-containing areas such as cytoplasm and ribosomal RNA pink-red. The result is a clear color separation where DNA appears blue-green and RNA appears pink-red, allowing you to assess chromatin patterns, transcriptional activity, and RNA-rich regions on the same slide. Other stains listed are general histology stains that don’t provide this specific DNA/RNA color differentiation.
