histonfehérjékhez
Histonfehérjékhez, commonly referred to as histones, are a family of proteins found in eukaryotic cells. They play a crucial role in the packaging of DNA into structures called nucleosomes. DNA, which carries the genetic information of an organism, is a long and thin molecule. To fit within the nucleus, it must be compacted. Histones act as spools around which DNA wraps.
There are five main types of histones: H1, H2A, H2B, H3, and H4. Typically, two molecules of
The interaction between DNA and histones is largely electrostatic, due to the positively charged amino acids
