Webchromosome banding is developed based on the presence of heterochromatin and euchromatin. heterochromatin is darkly stained whereas euchromatin is lightly stained during chromosome staining. a band is defined as that part of a chromosome which is clearly distinguishable from its adjacent segments by appearing darker or brighter
WebApr 26, 2024 · There are various techniques to stain chromosomes and achieve different types of banding. Here we mention some of them: 1. Giemsa staining: Giemsa is a visible light dye, which binds DNA through intercalation. Visible light dyes are more stable and capable of producing clearer bands than fluorochromes. thalamocortical interactionsWebEuchromatin (also called "open chromatin") is a lightly packed form of chromatin (DNA, RNA, and protein) that is enriched in genes, and is often (but not always) under active transcription.Euchromatin stands in contrast to heterochromatin, which is tightly packed and less accessible for transcription. 92% of the human genome is euchromatic..
