WebThese form large loops, which then get formed into higher-order chromatin structures. How compact the chromatin structure is helps determine how accessible the DNA is for expression; therefore, part of gene regulation can be done with modifications to the different orders of chromatin structures to make a given gene more or less accessible. WebJan 27, 2024 · Recent progress in chromosome biology has revealed three major types of chromatin loops in eukaryotes that are formed and maintained by different mechanisms depending on their function: loops that ...

It is a complex structure composed of DNA and proteins and localized in the cellular nucleus. Chromatin remodeling machines: require energy in the form of ATP and induce changes in conformation at the level of the nucleosome or more globally over large chromatin domains.
