Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene regulation and DNA replication. Without histones, …

4 天之前 · A histone is a protein that provides structural support for a chromosome. Each chromosome contains a long molecule of DNA, which must fit into the cell nucleus. To do that, …

2025年1月8日 · Histones are a major component of neutrophil extracellular traps (NETs) and kill microbes that become trapped in the web-like DNA. Specifically, the DNA serves as a net to …

2023年5月29日 · All DNA is packaged as structures called nucleosomes which are the basic unit of chromatin. Nucleosomes are composed of double-stranded DNA wrapped around an …

2024年11月4日 · Monoubiquitylation of histones H2A, H2B, and H2AX is observed at DNA double-strand break sites, playing a central role in the response to DNA damage. These …

The nucleosome, the basic building block of chromatin, contains 147 base pairs (bps) of DNA wrapping around an octameric core of histone proteins in 1.7 turns. The incorporation of …

2024年12月9日 · The DNA-packaging function of histones allows long DNA molecules, in the form of chromatin, to fit neatly into the cell nucleus. Histones, through the formation of chromatin, …

5 天之前 · Author summary The compacted organization of DNA within chromatin is primarily attributed to its intricate winding around histone cores. This winding process involves 1.7 left …

2021年8月1日 · The basic unit of chromatin is the nucleosome, that consist on DNA wrapped around a complex of histones. Adjacent nucleosomes are linked by histone H1/H5. It has been …

These histones bind with DNA to produce nucleosomes, the basic units of chromatin that are essential for compacting DNA and controlling its accessibility. Their dynamic control of …
