WebApr 6, 2024 · In our model, loop extrusion is performed by loop-extruding factors (LEFs), which may be a single SMC complex, a dimer of SMC complexes, or any other oligomer of SMC complexes. A LEF is comprised of two subunits, which can either be active or inactive. Each active subunit can processively translocate along the chromatin fiber, thus … WebMar 8, 2024 · Second, to characterize the possible biological relevance of the predictions, the enrichment of diverse chromatin marks at loop anchors was calculated. For the benchmarking, the 15-states chromatin models for GM12878, IMR90 and h1-ESC cell lines were downloaded from the Roadmap Epigenomics Consortium and analyzed as … rotisserie chicken oven recipe

Chromatin is a complex of DNA and protein found in eukaryotic cells. The primary function is to package long DNA molecules into more compact, denser structures. This prevents the strands from becoming tangled and also plays important roles in reinforcing the DNA during cell division, preventing DNA damage, … See more Chromatin undergoes various structural changes during a cell cycle. Histone proteins are the basic packers and arrangers of chromatin and can be modified by various post-translational modifications to … See more A variety of internal and external agents can cause DNA damage in cells. Many factors influence how the repair route is selected, including … See more It has been a puzzle how decondensed interphase chromosomes remain essentially unknotted. The natural expectation is that in the presence of type II DNA … See more The term, introduced by Walther Flemming, has multiple meanings: 1. Simple and concise definition: Chromatin is a macromolecular complex of a DNA macromolecule and … See more Chromatin and its interaction with enzymes has been researched, and a conclusion being made is that it is relevant and an important factor in gene expression.
