The tissue component stained blue-green in the image is?

Explanation:
Differential staining of nucleic acids shows DNA vs RNA. In many dual-stain systems, DNA binds the green-blue dye and appears blue-green, while RNA binds the red dye and appears red. Since DNA is concentrated in the nucleus (and in organelles with DNA), the blue-green structures point to DNA-rich material. RNA-rich regions would not appear blue-green but red or pink, and cytoplasmic proteins typically take up different stains and colors. Therefore, the blue-green stained tissue component is DNA.
