Heterochromatin and Euchromatin in the Nucleoplasm

In this article we will discuss about the Heterochromatin and Euchromatin in the Nucleoplasm. In the nucleoplasm of interphase nucleus a dark staining network is seen which is formed of chromatin. When chromatin is stained by various procedures such as the feulgen reaction which is specific for DNA and examined under light microscope, some regions are stained darkly whereas the [...]

Heterochromatin and Euchromatin

In this article we will discuss about the heterochromatin and euchromatin in eukaryotic chromosomes. The terms "heterochromatin" and "euchromatin" were given by Heitz in 1928-29, although they had been discovered much earlier. Heterochromatic blocks observed during interphase were earlier termed as pro-chromosomes. The substance of which eukaryotic chromosomes are composed is known as chromatin; it contains DNA, protein and a [...]
