Why nuclei are more receptive to dye?

Nuclei are more receptive to dyes due to their high content of nucleic acids, such as DNA and RNA, which have a strong affinity for certain dyes that bind to these molecules. Additionally, the dense structure of chromatin within the nucleus allows for increased interaction with dye molecules. The negative charge of nucleic acids also enhances binding with positively charged dyes. This property makes nuclei easily identifiable under a microscope when stained.
