A type of red dye used mainly in biology to stain and identify certain substances, particularly RNA.
The scientist used pyronine to highlight the RNA in the cell samples.
Pyronine is derived from the Greek root "pur" (meaning fire) and the suffix "-ine" (used to form adjectives or denote chemical substances). The word refers to a chemical compound related to or derived from fire or heat.
Think of 'fire' ('pur') when you hear 'pyronine', as it relates to a chemical compound associated with heat.
