Chromatin - Wikipedia
网页Chromatin 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.
Chromatin - National Human Genome Research Institute
网页2024年9月14日 · 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.
What is Chromatin's Structure and Function? - ThoughtCo
网页2020年2月15日 · 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 - Definition and Examples - Biology Online Dictionary
网页2022年6月16日 · 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.

网页Chromatin is a complex of DNA and proteins that forms chromosomes within the nucleus of eukaryotic cells. Nuclear DNA does not appear in free linear strands; it is highly condensed and wrapped...
Chromatin | biology | Britannica
网页…a dense, compact fibre called chromatin. An extreme example of the ordered folding and compaction that chromatin can undergo is seen during cell division, when the chromatin of each chromosome condenses and is divided between two daughter cells ( see below Cell division and growth).
DNA Packaging: Nucleosomes and Chromatin - Nature
网页These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Each nuclesome is composed of DNA wound 1.65 times around eight histone...
Chromatin - Biology Simple
网页2024年3月8日 · Chromatin, the structural form of DNA and protein in a cell’s nucleus, plays a critical role in gene regulation and DNA packaging. Changes in chromatin structure and function can have significant implications for human health, impacting the development and progression of various diseases.
Chromatin: Current Biology - Cell Press
网页2015年12月21日 · Chromatin is a complex of proteins, RNA and DNA that constitutes the physiological state of the genome. Its basic structure is essentially the same in nearly all eukaryotes, from single-celled yeasts to the most complex multicellular organisms (exceptions include the chromatin of dinoflagellates and vertebrate sperm).
