Euchromatin is a form of chromatin that is lightly packed—as opposed to heterochromatin, which is densely packed. The presence of euchromatin usually reflects that cells are transcriptionally active, i.e. they are actively transcribing DNA to mRNA. Euchromatin is found in the nucleus of eukaryotes and … See more Before understanding the structure of euchromatin, we should comprehend the different ways in which DNA is packaged in cells. The DNA in eukaryotic cells is arranged in … See more Although prokaryotes have a different mechanism to condense DNA, its packaged structure resembles that of euchromatin. It is therefore believed that heterochromatin—the densely packaged chromatin—evolved … See more Despite being actively researched, the structure of chromatin is still poorly understood although it seems that the cycle in which the cell is at a certain time determines the … See more 1. How is the switch between distinct chromatin conformations achieved? A. Through acetylation of the histones B. Through phsophorylation of the histones C. Through methylation of the histones D.
