Definition of Histones. Meaning of Histones. Synonyms of Histones

- tightly packed chromatin. Histones prevent DNA from becoming tangled and protect it from DNA damage. In addition, histones play important roles in gene...
- recombinant histones. One standard technique of loading the DNA around the histones involves the use of salt dialysis. A reaction consisting of the histone octamers...
- acetylated histones cannot pack as well together as deacetylated histones. Phosphorylation Ubiquitination SUMOylation However, there are many more histone modifications...
- chromosomes. Methylation of histones can either increase or decrease transcription of genes, depending on which amino acids in the histones are methylated, and...
- tetramer found in eukaryotes. Notably, archaeal single-chain histones, similar to eukaryotic histones, are found in the bacterium Aquifex aeolicus, suggesting...
- H1 is less conserved than core histones. The globular domain is the most conserved part of H1. Unlike the other histones, H1 does not make up the nucleosome...
- Acetylation removes the positive charge on the histones, thereby decreasing the interaction of the N termini of histones with the negatively charged phosphate...
- is wrapped around histones, and, by transferring an acetyl group to the histones, genes can be turned on and off. In general, histone acetylation increases...
- dephosphorylation of histones. Much like histone acetylation, histone phosphorylation neutralizes the positive charge on histones which induces euchromatin...
- histone proteins are: H1, H2B, H3 and H4. Histones are proteins that package DNA into nucleosomes. Histones are responsible for maintaining the shape...
