Chromatin - Wikipedia
WEBChromatin is a complex of DNA and protein found in eukaryotic cells. [1] The primary function is to package long DNA molecules into more compact, denser structures.
What is Chromatin's Structure and Function? - ThoughtCo
WEBFeb 15, 2020 · Chromatin is a mass of genetic material composed of DNA and proteins that condense to form chromosomes during eukaryotic cell division. Chromatin is located in the nucleus of our cells. The primary function of chromatin is to compress the DNA into a compact unit that will be less voluminous and can fit within the nucleus.
Chromatin - National Human Genome Research Institute
WEB1 day ago · Chromatin refers to a mixture of DNA and proteins that form the chromosomes found in the cells of humans and other higher organisms. Many of the proteins — namely, histones — package the massive amount of DNA in a genome into a highly compact form that can fit in the cell nucleus.

WEBJun 16, 2022 · Chromatin is a substance made up of DNA or RNA and proteins, such as histones. It condenses during cell division (mitosis or meiosis) and becomes a chromosome. Chromatins are “unwound” condensed structures whereas chromosomes are highly packaged and more condensed than chromatins.

WEBChromatin. The complexes between eukaryotic DNA and proteins are called chromatin, which typically contains about twice as much protein as DNA. The major proteins of chromatin are the histones —small proteins containing a high proportion of basic amino acids (arginine and lysine) that facilitate binding to the negatively charged DNA molecule.
