Which of the following is true regarding aceto-orcein staining? The active dyes in this strain are small, extremely hydrophobic anionic dyes. Orcein can be extracted from three different species of flower. Staining occurs via hydrophobic bonding and van der Waals attractions. Is ineffective for staining as DNA is soluble in acetic acids.
